Your choppy sound problem sounds like it may be caused

I suggest you disable it in the settigns. I think
there is an option in mythtv-setup and the general
settings.
Nick,
Sorry that it has taken me so long to get back to you - I've been on
holiday and then had to rebuild my myth-box after the disc got trashed...
I'm not running any commercial skipping stuff. I guess that would be
run on the backend anyway, wouldn't it ?
The problem occurs on my frontend box which is using XvMC MPEG
decoding and only taking between 5-15% cpu.
Box is an EPIA VIA Ezra 1gz running 2.6.12-1.1378_FC3, FC3,
xorg-x11-6.8.2-37.FC3.ucr.30.8 and
kernel-module-via-drm-2.6.12-1.1376_FC3-2.6.3-2.ucr
(http://washington.kelkoo.net/epia/FC3/RPMS/) and latest myth from
atrpms (0.18.1-114) with libmyth-0.18.1-113.rhfc3.at. I haven't been
able to upgrade past this version of unichrome because of issues in
later versions on my architecture.
Sometimes the choppiness occurs throughout the whole recording,
adverts and main feature, sometimes the adverts are fine and it
appears as soon as the main programme starts.
I've tried playing with some of the other settings to no avail.
I have tried disabling XvMC in setup to see whether the choppiness is
associated with that, but curiously this seems to have no effect and
the log still talks about VLD Surfaces etc...
So, I've now tried rm-ing my /etc/X11/XvMCConfig, commenting out the ref
to "dri" in my /etc/X11/xorg.conf, rebooting, disabling XvMC in the
setup menu and playing back a recording, but mythfrontend still insists
on trying to use XvMC and fails to play completely :-(
Does anyone know what is happening and how I can get myth to run without
XvMC support, just to see if this sound issue is related to XvMC or not ?
Cheers,
Jules
If I play the same recording on another box (dual opteron x86_64,
without h/w MPEG) it runs fine without choppiness. I guess I will have
to work out how to switch off XvMC on my Via and run some more tests....
Anyone any ideas?
cheers,
Jules
