hmmm.  The append doesn't seem to work quite properly.  I tried connecting
for 58 seconds, then 44 seconds. Here's the result:

I discovered this because a friend using oddcast did a show that resulted
in a server-side log that wouldn't play in winamp, but would in ogg123.
I'll post the ogginfo for that too, but youll see that, apart from the 0
byte count for stream 1, the output looks very similar. any advice on what
can be done to doctor the below file to make it playable would be good as
it's 60 meg and I don't particularly want to compromise quality still
further by re-encoding it, assuming that oggdec will decode it.

Processing file "Dave and Friends.ogg"...
