Hmm.. I never noticed it before, but it would appear that I have the same
problem. Though it MAY just be the stream, I only tried with two *remote*
streams as I have no local ones to test. I found that video content was
about 4 seconds behind the audio content..
I do not have any of the 'weird sound' problem though. I did through XMMS
but their new version fixed that out. Similar problems occured with things
that used certain mixers. I believe this was an issue of the *program* not
the OS. Either way, xmms 1.2.x fixed it.

I've attached my dmesg incase there are some similarities.
