I´m trying to use Cyberlink Power DVD (version.6 and 7) to watch DVDs, but
I´ve got a black screen instead the video and audio only. The funny is that
if I use Media Center I´ve got the video but no audio (I know there is a bug
with audio codec if you are using AMD XP cpus). But if I use a decoder
utility to switch the decoder from MS to Cyberlink decoder the dvd runs fine
in media center (but not in Power DVD). Does anyone know what I should do to
watch DVDs in Power DVD? BTW I have a Radeon 9600 card and using build 5728.

Solved: just don´t use the RC1 beta driver from ATI site.
