I was just watching an Idols Extra recorded today and there were 
multiple out of sync situations that were allways fixed by a 10s 
backwards jump. I could not see anything in the picture (like periods of 
black etc.) that would cause this. To make the best of this I should 
make the whole recording available somewhere because I would not know 
what to take out of it. And that is not very convenient because of the 
size of the file.

This is what was in the log if this is at all relevant.

As you can see the recording was on the way as I was watching it.

I've removed two channel events and one ntp event from the log output.
