Hey Blue Ray shoppers.Please be aware that this Blue Ray will not play a lot of dvd's (1/4 of my collection) . After I bought my first Blue Ray disc I found out that I need to update it and I need to wait 7-14 business days before Samsung will send me the disc.Costumer support was horrible and mostly useless.Most of electronics I own are high end Samsung but looks like I will be considering all other brands after this expierience.
