I must say I played with codec and it "appears" (didn't have intensive tests) that it works, I'll post my results in one week since I'll be in vacation.
Have used PDVD 6, Purevideo and MPA/V and happens with all of them.
Additionally the Wife (big channel surfer), tells me that it happens if she changes channels too often.
I don't surf but use the miniguide instead.
I'll be happy to investigate in detail if someone can point me in the right direction. Generally speaking hitting pause/play will fix it. Sometimes though the only way is to exit and restart MP.
Turning off timeshifting removes the problem but that isn't the purpose of a PVR
try changing the audio renderer for tv... you have to do it via the mp gui (not config), and go to settings->my tv->audio renderer.
when i changed mine over (can't remember what to ) it fixed the stuttering tv problem i had!
I've finally checked the log file (attached), but can't find anything weird. Procedure followed:
1. Perform restart (MP will load automatically)
2. Press LiveTV
3. Watch channel for 5 sec (in window) and assess quality (good)
4. Press the green button --> go home
5. Press Standby (on MCE remote) --> system goes to S3
6. Press Standby again --> system wakes up and shows MP in home screen
7. Press Live TV
8. Watch channel for 5 sec (in window) and assess quality (stuttering)
This is resolved if I close down MP and restart MP, which is a bit unpractical. There is no difference watching in window (Live TV) or full screen.
It seems as if this can be fixed with pvr-scheduler, since it can start MP before a recording and shut it down afterwards. There are now new versions working with MP 0.2.2.0 or SVN. The only catch is that you have to donate at least 5 euro if you want to try it. http://www.pvr-scheduler.de/
I've been using PVR-Scheduler for some time now, and it's worth every cent you donate. It has allowed me to reliably use my HTPC without having to leave it on all the time .
