I've only seen these errors when IPV6 is enabled... Try to recompile
ffmpeg without IPV6 support.

Ok, I see this one too... But it is just one single error at the
beginning of the stream: I do not think it is very important (the stream
is received ok)

I do not know what to say here... It seems that you are receiving
corrupted data or that you are loosing a lot of packets.

I just tried again: I did a fresh cvs checkout, applied my patch,
configured, removed the IPV6 define from config.h, compiled, and
everything is working fine... Both ffplay and vlc are perfectly happy
with the stream. Which version of ffmpeg are you using? Can you try a
fresh cvs checkout?
