Re: [mythtv-users] Jerky MythTV on a M10000 even with working XvMC. Help!

[Matthew Sullivan]

I'm recording in 480 x 480. I tried to change them around, but=20
unfortunately it had no effect at all, but thanks for the tip.

I've continued to play with the thing and discovered that MythTV will=

playback recorded video just fine, no jitter at all. So the problem i=
s=20
only in combination withh record and playback. And as I can watch liv=
e=20
TV fine through an iBook connecting remotely to the backend, the=20
problem must lie with the frontend of MythTV on my M10000 box, most=
=20
infuriating as I have 0.15 working perfectly on it!

Stats wise, things look as follows:

Playback of recording is using about 15% of CPU (XvMC must be working=
=20
nicely).

Playback of live TV, i.e. while recording, CPU usage is Mythfrontend=
=20
15%, mythbackend apprx. 10%, with tons of CPU usage still available. =
So=20
processor isnt the bottleneck...
