So far, merely WinDVD works. Inter Actual Player, Windows Median Player, and HotLlama Player won't work. On Inter Actual Platyer, I get a message proverb...
"Playback bungled due to a problem beside the video subsystem. Lowering your peak resolution or color depth may fix the problem "
Why can't I use these other programs?
Answers: Hi.
I'm not sure why you're getting an error, but you may want to update/upgrade your video card drivers to the most modern variation. The two video card manufacturer are ATI (now owned by AMD) and Nvidia. You can download the drivers for your video card at their respective websites, which I've scheduled below.
ATI:

Nvidia: www.nvidia.com
Also, you may want to try using VideoLAN to play your DVDs, which is adaptable medium player and plays a widespread mixture of formats.

Hope it help!
