Hi - I have an M6000 and have just finished setting it up with version
0.18 . MythTV is fantastic despite my fears over the relatively
I am running Gentoo and have an Avermedia 771, so am getting an mpeg2
stream which means less CPU used for mpeg2 decoding with the unichrome
mpeg2 card. I am running backend and frontend on the same box with no
When I run anything without hardware acceleration, the CPU maxs out and
the pictures lag a bit. When acceleration is on, I get about 40% idle and
the picture is perfect. Even when I play an xvid file with mplayer and an
xv driver, I get 50% idle.

you compiled Myth and your kernel with Unichrome support? What distro are
NOTE: Even when hardware acceleration is on, you will get "prebuffering
pause" messages. I have got over this by running mythfrontend with nice -
