Hello all,<br><br>I have a really annoying problem. My main frontend now has horrible choppy pauses whenever I try to watch something (worse on HD recordings but alsso affects non-HD). I really don't know why this is happening. I didn't change any hardware. This has been a stable system for over 12 months and it worked fine for weeks after upgrading to mythtv 0.21. I can use my second frontend without any problems. So I don't think the issue is with the backend.<br>
<br>Here are some details about my setup:<br>all computers are running ubuntu 7.10 and mythtv 0.21 (I do not compile it myself)<br>dedicated backend -> duel intel Xeon 2GHz<br>dedicated frontend (has problems with playback) -> intel core 2 duo 1.8GHz, nvidia Geforce 7600GS<br clear="all">
desktop with frontend (no problems with playback) -> intel pentimum D 3GHz, nvidia Geforce 7800<br><br>There does not seem to be any bottle necks that I can find. The CPU load on the frontend doesn't look critical during playback.. I have a gigabit network which has been plenty fast for over a year.<br>
<br>Here are some of the error messages mythfrontend outputs:<br>2008-04-30 21:56:27.977 NVP: prebuffering pause<br>2008-04-30 21:56:27.983 WriteAudio: buffer underrun<br>2008-04-30 21:56:29.357 NVP: Prebuffer wait timed out 10 times.<br>
