[mythtv-users] Smoothing out playback?

Some news here :

I am now using the debian-multimedia package (version 0.20-svn20070223-0.0) on all my boxes (b/e and f/e's). If fixed liveTV on one of my f/e's but I still observe the same problem on another one. More precisely, liveTV works fine for half a minute and then pauses about 2 sec, resumes playback, pauses 2sec, resumes again, etc. The log messages related to this behavior are :

2007-03-10 12:25:10.895 Checking to see if there's a new livetv program to switch to..
2007-03-10 12:25:11.955 NVP: Prebuffer wait timed out 10 times.
2007-03-10 12:25:13.019 RingBuf(/multimed/mythtv/livetv/1006_20070310122457.mpg): Waited 1.0 seconds for data to become available...
on and on ...

It looks like it's trying to switch to another program periodically but it's always switching back to itself.

Did anybody observe such behavior ???

there are a few small things that the official 0.20 release does not have but considering that liveTV playback is screwed in my system, I will fall back to a more stable version.

Isn't svn the testing/development branch?  I imagine it would not 
function properly all the time.  Given that it's a testing branch, 
perhaps a detailed bug report would be more constructive.  Is there any 
reason why you have to run svn?  Particular hardware support?  A must  
have feature?  I've been running myth since 0.5, never really had a 
problem with it outside of the occasional bug.  But then again I've 
always ran a stable version.  Perhaps a regression to the 0.20 fixes my 
be advisable.
