This makes video streams hard to watch, and also cuts off local : streams early. Also, on remote streams, the sound clicks and squeals loudly : about 1-2 seconds into the stream, and the stream stays out of sync with the : RealPlayer counter the whole time. I have a PR open on this, misc/18728. 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. : All of this seems to have started happening around the time of the May 12 : MFC, it looks like.
