I could imagine changing my GFX card, I seen that some nvidia has
onboard mpeg2 encode/decode up to 1920x1080i BUT they certainly miss a
linux driver for it ???
It would be perfect to have it use the hardware of such a card :-)

Great to know, any idea on when that wil change ?

Just starting xine-plugin for HDTV, the quality of xawtv for normal
watching is much better. And last but not least, xawtv/xorg takes less
than 0.1 % of my CPU :-)

Well, I don't have a TV... and yes for fast switching betweem
xawtv/xine.

No, I want to demux, remux, transcode :-)
