vista playing dvds

I have read somewhere that all but the newest DVD drives in a PC will not be able to play DVD movies on a Vista system. However, any will be OK reading & writing data DVDs. Can anyone confirm or deny this & if its true how can I tell what ones should be fully compatible?
There does not yet seem to be a proper HCL.

Well, not entirely sure but I see what you mean. In XP, you couldn't ordinarily watch a DVD in Media Player 10 because it didn't have the codecs there - you actually had to buy or download a DVD player. Only then could you watch them in Media Player if you wanted to because the codec was there.
Reading and writing DVD's are different - they don't need codecs at all. The only reason you need a codec (compressor-decompressor - similar wording to "modem") is because the video/audio stream is all jumbled up and you need a bit of software for XP/Vista to see it properly.
Hope that explains it relatively OK :o)

I read that Vista won't support any dvd drives that don't have the dvd region hardcoded into them in firmware. All dvd drives have had this for about 6years, so it shouldn't be a problem.

I think I know what you probably read Keith, Vista won't natively support (Sony Blu Ray DVD's), support will have to come from third party vendors, on the other hand existing generic DVD-ATA will be supported and the Microsoft backed HD-DVD will also be supported natively in Windows Vista. -- -- Andre Windows Connected | http://www.windowsconnected.com Extended64 | http://www.extended64.com Blog | http://www.extended64.com/blogs/andre http://spaces.msn.com/members/adacosta
