[mythtv-users] MPEG2 acceleration with PUNDIT-R (9100 IGP)

[vala ki]

As the ATI site specifically states :


   - Integrated hardware motion compensation and iDCT
   - Enhanced MPEG-2 hardware decode
   - Hardware DVD sub-picture decode 

here : http://www.ati.com/products/radeon9100igp/features.html

so.. it's a matter of finding apropreate drivers that support these 
features......
as most modern cards support MPEG-2 hardware decode it would be a shame to 
use the CPU for such tasks.....
