The fact that DVD discs can be upconverted all the way to 1080p is one of the main things that really killed off Blu-ray. Now, people don't need to repurchase their entire collection of DVD discs with those over-priced Blu-ray discs.

WRONG if u upscale a dvd to 1080p you will get about 20mins of footage on it if that and am sure u will agree last thing i want to do is watch a full hd film and i hav to keep changing the discs evry 20 mins

Space - Sony claimed that Blu-ray had the advantage of "space" over HD-DVD because Blu-ray stored 25GB per layer, while HD-DVD stored 15GB per layer.

Sadly, we now know that it was HD-DVD that had the advantage of "space" over the Blu-ray. The "standard" sized disc used by HD-DVD movie discs was 30GB in size, because the disc was dual-layer. The "standard" sized disc used by Blu-ray movie discs is only 25GB, because the movies use only single-layer discs, because of the fact that the dual-layer discs have such a high defect ratio that they are very expensive. This gives standard HD-DVD movies discs a 5GB advantage in the area of "space."

more bull crap blu ray single has 25gb but hd dvd has 15gb a double sided blu ray has 50gb while hd dvd only 30gb and now the blu ray disc can get upto 400gb of space on

Sadly, Sony decided to tell more of their lies by saying that Blu-ray would do the same...Blu-ray has been on the market for several years now, yet it still does not have any hybrid discs.

my bullcrap i have casino royale on blu and its a hybrid but its not dvd on the other side its the extras which in my opinion is a lot better

so in my opinion you should go back to your cave you little xbox fanboy and learn what your talking about befor you start typing aload of shit

oh and its funny how blu ray is still going unlike the so called better one hd dvd which is a big fail which xbox fanboys cant handle
