Hi all, I've got a couple of strange problems with Power DVD XP 4.0 on my newly built HCPC with a Radeon 8500DV card and ATI Catalyst drivers ... 1. The playback quality is very very bad, the picture looks like it is split into vertical segments which look like the picture is splitting vertically ... can't really describe it too well! 2. If I select 'Play Media file' from the 'Play' menu ... the program (and sometimes the PC) hangs rather than displaying the next window. As I use the same version of Power DVD on my other 'office' PC with no problems (has a GeForce2 Ultra and Nvidia detonator drivers), I'm wondering if its a conflict with the ATI gfx card and/or drivers? Anyone encountered similar problems? Please help!!! Cheers, Mark.
