Query: mac user stiffed again

I watched this originally in the iMax theatre and was very impressed by it, and finding out now that is was available on dvd was so much better....but that is where it stops...I have a HD projector and 7'x8' screen and this was low quality, just like any other dvd, it is not in HD, the extra wmvwhatever dvd is in HD but it is strictly for windows based systems, I use a stand alone dvd player and my powermac G5 for movie playback and was stopped dead in my tracks due the windows only dvd, in a sense there is only one dvd in the box that can be used while the other will be used as a coaster. No matter what you try on your mac or other non-windows based computer the dvd is locked for microsoft only. I do not know why this company decided that windows is the only operating system on the market but I guess they are not familiar with HD rendering. So if your happy with a mediocre picture and have a windows computer hooked up to your TV this is the dvd for you.
