I have a AOpen i915GMm-HFS motherboard with a 1.8GHz Pentium M CPU
running Debian Sarge standard install with Mythtv from the
debian-multimedia repository. Attempting to playback HDTV results in
severe frame dropping and for me the Xv acceleration does not work
(blue lines across the screen, probably old driver, not sure), so the
CPU has to do all the work. The only solution I can find that works
now (and allows me to keep my main board) is to get an NVIDIA card and
use the closed source drivers. Another thing to keep in mind is the
quality of the image processing, have a look at this article:


Then off course you need $8000 to buy a screen that can actually
display the image ;).
