I've been having audio sync issues lately. I'm running R5D1 with XVMC, and I have plenty of remaining CPU cycles while I'm watching. (CPU is at most 50%) My commercial flagging is deferred until the middle of the night, so I know it isn't that.

I've also noticed that playback is not as smooth (and the unsynced audio issue is more noticeable) when I am watching an HD recording at the same time that another HD show is being recorded by my HD5000. The video isn't choppy, but it definitely isn't 30 fps. While the CPU usages is only 50%, I've found that the load is sometimes 2.x or 3.x. Why would the load be high when the CPU has plenty of cycles left?

Could be WAiting on I/O? Run "top" and check the WAit percentage.

make sure that you have disabled 'OpenGL vertical sync for timing'. I found that I needed this set for R5A30.2, but I needed to disable it for R5D1...

Already disabled it.
