Hi All

I hope I am in the right forum if not please pass to the correct one

I Purchased a DVD called Amazing Caves, it came with a bonus disc which has High definition WMV files on it,
all of which play fine except for the main title tracks
It seems that these files have DRM on them and do not like my sound card
I have tried the AC97 built in sound card and a plug in Sound Blaster live sound card but it does not make any difference

I get an error message C00D11B1 while using Windows Media Player
"Your sound device, such as a sound card or sound controller, requires an updated driver"

Is there an approved sound card that will allow me to play the 2 files called
"AmazingCaves720.WMV" and "AmazingCaves1080.WMV" each about 2.5Gb,
on my computer as I hope to obtain a HDMI video card and connect the PC to my Sony HDTV

any help gratefully accepted

Regards
