Just verifying that I understand it correctly: this also happens with a non-trunk ivtv release, correct? So it is not some ivtv trunk bug that is hiding somehwere.
Correct, this problem is the same with the trunk as it is with recent ivtv-0.8 With 16 MB of buffers that should give you somewhere between 10-16 seconds
of buffering I think. I find it hard to believe that MythTV would take so much time! You can easily check how full the various buffers are by running v4l2-ctl --log-status.
