[QUOTE="Frodo, post: 111738, member: 10277"] Seems there is a lot of interest on this subject, and also a lot of false information. Let me try to clarify things a bit [b]Hoax #1 : You cannot playback full HD media files on a Vista pc.[/b] Wrong. You can play HD (High Definition) media files (like 1080p) just like you can under windows XP, linux,... They wont be degraded or scaled down or whatever. !!!But!!! if your HD media file contains DRM (a HD-DVD for example) then (and ONLY then) you need a drm-compliant system. A drm-compliant system is a system which supports a protected path from dvd ->player->os->video card->tv. [b]Hoax #2 : Vista downgrades HD media files to lower quality.[/b] Again not true. - Vista happily plays HD media files in full quality if - the files don not contain any DRM - or if the files do contain DRM and your system is drm-compliant Now what if you dont have such drm-compliant system, what then ? Actually it depends on the DRM itself. The producer of the HD media file (the movie industry) then decides what can be done. The HD media contains information which tells the system what can be done (and what not) on a non-drm compliant pc. So.. the in the end the producer tells the player to either: - not play the HD media file at all, or - play the HD media file, but downgrade the quality to SDTV, or - disable the digital audio output or - disable audio at all - ... A lot of people blame vista on downgrading quality of HD media files. I hope you now see that this is only done when - the HD media file contains DRM - and only when your pc is not drm compliant. - and only if the producer has specified that the HD media file should be downgraded on non-drm compliant pcs Sadly not vista, but the movie industry is to blame for this. [b]HD-DVD on other operating system ??[/b] Also look at it from another perspective. Vista is the first operating system which allows you to play drm-ed HD material. Offcourse a requirement is that your system is drm compliant. But does linux, macosx, windows xp or any other OS allow you to play back HD-DVD drm-ed media files in full quality ?? No you simply cannot playback drm-ed HD-DVD at all on these operating systems! [b]Hoax #3 : Vista disables the digital audio output for HD media.[/b] Again, not true. This is only done when: - you want to play HD media which have DRM - your system is not DRM compliant - the producer specified to disable the digital audio output on non drm compliant systems In all other cases, digital output wont be disabled Now DRM is something we end-users dont like, me included But its there, The movie industry will not release any HD material without proper DRM. So they way i see it Microsoft had 2 choices when developing vista. 1. Don't add DRM support in Vista, this would mean you could not playback HD-DVD (with DRM) at all 2. Add DRM support in Vista, only use it for media files which actually require DRM. This will allow people to playback HD-DVD (with DRM) if they got a DRM compliant system. Again, i don't like DRM, but i'm glad they choose #2 since now i have the possibility to watch HD-DVD. Offcourse i'll have to make sure then that my pc meets the drm requirements... But in the end, the choice is up to me. Under linux, macosx, windows xp i dont have this choice. I simply cannot playback HD-DVD with drm at all... Frodo [/QUOTE]
