[mythtv-users] Strange problem with jerky playback speed just in live tv - V 0.19

[Doug Scoular]

Hi Matthias,

>or shorter, this is not fixed. Eventually, it gets smooth after some time (I 
>saw this once, when I left it playing for a couple of hours without

>5000kbit/s; when playback is smooth, the packet flow also looks smooth. Same

    I have this same problem with 0.19-fixes svn. I have a DVB-T setup, 
whenever
    I watch livetv I see the video subtly alternate between slow and 
fast play. I mentioned
    this on the #mythtv-users irc channel, a while back, and someone 
responded that it
    was a known issue among the developers, but no-one had managed to 
track it
    down. The work around, they said, was to pause and then unpause livetv.
    This works perfectly for me. Note that my system is a single 
backend/frontend
    box. It's only a slight annoyance.

    Cheers,

    Doug
