I have lost two different DVRS and one Blu-ray due to lighting striking close by (we get a lot of lighting where we live). After installing this unit, I have not lost any electronics after almost a full season.

I'm very sorry that I cannot recommend this system.  It replaced my old 4-camera DVR when I bought 4 more cameras (total 8 now).  I really do like this DVR and its features, but it's just not reliable.  On a few occasions we found that it did not record footage that we were searching for because at some point it had stopped recording which created a lapse of weeks; we don't know when it stopped, but that's okay since the footage was not crucial.  A surveillance tech friend suggested drive failure, so we replaced the drive at our cost and started over + tested + made sure it was working.  This time we were broken into about 2 weeks ago and there was no footage to access again for police.

I have seen it restart itself when it emits a loud beep usually once every week or two; I suspect this is the point where it turns to Live View only and stops recording.  The problem is that I'm not always there to hear the restart beep to know that I have to put it back onto Record mode again.  It would be okay if it showed an obvious indicator when it's on Live View mode so that I can turn Recording back on, but it doesn't and it's a bit too much work for me to test on a daily basis.  I've owned this system for 14 months and I'm sorry to say I cannot recommend it.

This let me down.  I've had it for a while, working perfectly.  All the sudden, the TVs periodically lose signal.  It's only about a second, but it's enough.  I thought it was the cable but the DVR recordings don't have the signal losses that show up on the TV.  I finally unplugged the splitter and plugged the DVR back into the TV with no splitter.  No lost signal anymore.  Put it back in the splitter, the signal losses start again.  It really shouldn't have failed this soon. Very disappointing.

Tivo isn't what it used to be from a hardware/software/customer service perspective.

Hardware - I purchased a Tivo Series 2 in 2001 that still works (although it's SD, so we don't use it with service anymore).  I have gone through 3 other units since 2010 and all have had hardware failures past the warranty.  Although this may be a small sampling of total units sold, it is an unacceptable failure rate.  I also made the mistake of purchasing lifetime service on one of the units which vanishes with the hardware failure.  The service does not transfer to a new unit.

Software - The first versions of Tivo "just worked".  It was a slick interface, responsive and reliable.  They have added many features since that first version, but one of the unintended features is that the software is no longer snappy, has glitches regularly, reboots itself in the middle of recordings regularly (losing the recording) and stalls in the middle of playback regularly.  It's no longer the reliable workhorse that it once was.  Not sure if it's just because they are using cheaper hardware coupled with cruder programming, but the units now feel crude often versus refined.  They are a more of a source of frustration than before.

Customer Support - This used to also be a strong suit.  This has declined considerably.  Probably as a cost saving measure to slow their financial bleeding, there are now customer service "games" that I'm sure most customers don't enjoy (at least this customer doesn't).  For example, because of the hardware failures, I have needed to cancel the monthly service on a unit I did not have a lifetime plan on.  Since there is no online method of cancelling, after calling to cancel, nothing happened.  However, because I was getting billed for another Tivo unit, I didn't put two and two together that I was still getting billed for the cancelled unit.  I just assume it was done as they said.  I called them to let them know so they can rectify and was told that it was my fault and there was nothing they could do.  They insisted I didn't call (because customer service systems are never erroneous) and that even though they could verify that the unit has not connected to the service in a considerable amount of time, it didn't matter.  They related their customer service to that of a cell company.  For the record, my cell service provider has had excellent service and I doubt that this matter wouldn't have been resolved by them.  Long story short, don't count on customer service to do what's right by the customer, count on them to follow internal policy which saves Tivo some much needed money.  Also note that with all of the tech available, they don't let you cancel service online.  Clearly to make things more difficult for you to cancel and to give them a chance to sell more to you.

Regrettably, I recommend people look for an alternative to Tivo and save themselves aggravation.  Even if customer service doesn't come into play for you, the hardware/software issues will ensure that you don't have a great experience.

I would give it 5 stars except for two things. The first one I received was DOA. It just kept rebooting. The second one is working fine. The other issue is the funky file names it gives when saving programs. This really isn't that big of a problem since I'm not making a huge collection. I'm using a 32 Gig thumb drive. This lets me save a bit over 24 hours.
Some reviews say that set up and the menu system is a bit confusing. I don't find that although like most electronic device of this nature does have a bit of a learning curve to really use it. I should add that I am not using the converter feature but only as a DVR. My TV is already digital capable.

The thing I really like is that I'm using the AV outputs to drive my TV. This way I can record programs with this while I watch a different channel on my TV.

I purchased this SD to use in the Car Dash DVR I purchased in March, 2015. I used it for one week then put it away. I was moving pout of state and packed it to not get lost or broken. In September 2015 I found it and started using the SD and  Dash DVR. After fur days in use the SD card crashed, just stopped recording. I removed the card put it in my PC to see what was wrong with it. By just being in the DVR recording the last file became damaged. I have no idea how since I was in a store when it happened, came back to my vehicle and saw the DVR had stopped working.
I tried to re-format the SD, delete files and repair the file. The SD will not respond. I don't understand how an SD card becomes damaged for no reason at all. I formatted it before using it, it is the correct size and model for the DVR I have so what happened? A defective card? Don't know but I wouldn't and will not buy this SD again. Now I have to buy a new card for my Dash DVR. A waste of money and time.

This dvr has served me well. The tech support people answered my questions right away by email when I  loss video. It wasn't because of the dvr that I loss video, it was because the power cord to the power box had slightly come out of the power strip and I didn't know it. After giving tech support all the required information and sent pictures, it was determined that I check the power supply box and that's when I made the discovery.  I would recommend this product as I have had no issues with it and I love the features.

What I hate is that this set was a replacement for the first set.  Both sets had video and audio problems at the same spots.  When I sent the first set back, did you even send me a replacement or did you send me the same one I sent back to you? Interesting,huh.

My old remote for the Polaroid DRA-01601A 160GB DVR had died a few weeks ago, and I thought I was going to have to purchase a new DVR altogether.  But then I found an exact duplicate of my dead remote through Amazon from Awesome Remote Controls.  Just got it today and everything works again!  Will order a second one as a backup.  Thanks!

I've had this product for a couple of years and it works great.  I purchased this item after our Directv HD DVR Satellite box went bad and we lost all of our recordings when we shipped the box back.  I liked the idea of the extra storage capacity, but primarily purchased to have a back up of our recordings - in case we were faced with losing them again.  Well, our receiver had another problem recently.  I connected the DVR expander to the new receiver and everything appears to be okay until you try to watch a recording that was made on the old receiver.  Apparently (through some online research,) the recordings made on the DVR expander are hard linked to the receiver.  You can't move the recordings as I assumed.  They old recordings are all visible and new recordings show up and work fine, but it didn't transfer as one would assume it would.  I'll have to wipe the drive clean to free up the space.  Can't find a way around this.  Works great - but only as a DVR expander - will not protect your recordings if you're receiver needs replaced.  May be a way to extract to your personal computer, but not practical if you want to watch them on your TV.

Last year I purchased 2 Channel Master DVR+ (for approx. $500.00) hoping to cut the cord get rid of cable.  I found that the software had quite a few problems.  First, the guide was not accurate and only went out 2 days.  After 6 months they send out a patch, and now I can see 2 weeks of the guide, a vast improvement.  However, the guide still does not match that is on the channel for a couple of channels.  The guide for one channel shows the programs on another channel.  Makes it a real pain when you want to record a show....

Now the worst of it all.  The first unit I bought did not come with a internal hard drive.  The one they shipped with the unit was from Seagate.  Worked fine until last week...  and just died.  Tried using it on the other unit, and it too did not work.  Tried a few other tricks (including seeing if my computer found it) again no luck.  Time to bury that drive.  Then I thought I'd move the DVR+ that had the internal drive to the other room.  I thought, I have a lot of recordings on it so lets just reformat the drive instead of deleting each show.  Use the setup reformat setup option, and it crashed during the formatting process.  Now it tells me the disk is not readable.  So I'm out of luck on that one too.

To top it off it only has a 90 day warranty.  I'm screwed.  I hate to say it, but it's time to dump this approach and look at other options.  When you pay this much for a product, you would think they stand behind the product for more than 90 days!!
