This is when the cache becomes full and MPlayer has to wait more than ca.
100 ms for any new data to arrive. You are only lucky enough to not here
this when there is a lot of buffers (also for the uncompressed audio)
It's an indication that something is going wrong, in this case you
probably should be chosing a larger cache prefill value (or larger
cache size, has the same effect since prefill is in percent of

Yes, I had noticed that before, I just forgot to commit it :-)

This is probably related to some commands like setting up the channel take
a huge amount of time.
Currently MPlayer can't distinguish between this and an actually hanging cache.
So far I think those printouts are doing the job they're intended to do, however
I'm not fully decided on that yet.
(note that I mostly added them because it's not the first time the cache process
was killed and users were left scratching their head what is going on - this should
at least give some hint).
