Time line causes audio problems.

Moving the mouse in time line the message log shows:

main warning: output date isn't PTS date, requesting resampling (54000)
main warning: output date isn't PTS date, requesting resampling (44021)
main warning: audio drift is too big (130645), dropping buffer
main warning: audio drift is too big (123395), dropping buffer

And then,sometimes, after some seconds there is a little cut in the audio stream.
