The time display in xmms goes back and forth between two values. It
counts like 02,01,02,01,02,03,02,03,02,03 so it does actually go
forward. The audio sounds fine. It's just the display doesn't look right
and xmms locks up at the end of a song.

I think it's in our .transfer callback, a2dp_transfer. I had two
versions contributed. The other version, a2dp_transfer2, randomly locks
up xmms but when it works, the time display looks ok and xmms can switch
between songs without problems.

We have to enforce timing of packets sent to the headset in the
.transfer cb. Is there a plugin out there I can look at that also has to
deal with timing? We're not sure how to best enforce it... see
