Interesting. I have my front end (Acer Revo) seperate to my backend (Core i3) and it seems pause when the backend CPU goes to 100%. In all cases its with mysqld when its running one of the scheduling queries. Perhaps when the backend CPU is busy the frontends get momentarily starved of data resulting in both audio and video buffer underruns. In my last mail I was suggesting some query optimisation. I was wondering if there was some temporary workaround; e.g increasing (or decreasing) my ALSA or VDPAU buffers. Or maybe something with mysqld so that it doesn't lock up the entire machine. With a my multi core CPU I'm amazed it does go to 100%. Maybe there's some other bottleneck.
