Just upgraded from karmic to lucid and hit exactly this problem. VERY noticeable on the heavily inter-cut World-cup coverage on ZDF and ARD here in Germany.
Seems supiciously like a "reincarnation" of http://svn.mythtv.org/trac/ticket/7522 this was fixed 0.22-fixes. Could it be the ffmpeg upstream fix isn't present in the ubuntu 0.23 builds? ** Bug watch added: mythtv.org bug tracker #7522 http://svn.mythtv.org/trac/ticket/7522 -- MythTV playback issue - number of reference frames exceeds max https://bugs.launchpad.net/bugs/585263 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
