[mythtv-users] Myth on the Epia M10000

[BARKER, Paul]

Hello all

If you read my posts of last week you'll remember that I've been trying to
build a frontend on an Epia M10K system to replace my current large frontend
box that used to be a combined fe/be.

I'm having big problems trying to get live TV and recordings to run without
either audio out of sync messages (which results in dropped frames) or
prebuffering pauses.

The current fe is an Athlon XP1800 with 512Mb of RAM and my LiveTV recording
profile is full PAL res at 720X576. (The b/e uses a PVR250)

On the Epia box if I try to watch live TV or a recording recorded at this
resolution I get choppy playback. If I drop the resolution to 360x576 things
are pretty smooth. My CPU isn't pegged and I've turned off swap, switched to
alsa and upgraded to the latest alsa kernel mods all as suggested in
different posts on this list. I'm intending to use MythCVS so I can use the
CLE266 h/w mpeg stuff and have tried various builds of the Unichrome drivers
and MythCVS with varying results. I've also put another soundcard in and
disabled the onboard sound. I'm at a point where I seem close to getting this
to fly but it's taking up rather a large amount of time.

I guess my basic questions are  

1) Is anyone out there running Myth using the Unichrome drivers on an M10K
and using native PAL resolution without problems ?
2) If yes do you use the onboard sound ?
3) Am I in overkill land with the 720 x 576 recording profiles ? (I was
trying to minimise any filtering or scaling)

If I know this *should* work and is possible I'll keep plugging away but I'd
like to know if I should just stop banging my head on the brick wall and
switch to a lower resolution ;-)

Cheers

Paul
