I have been having similar issues as you describe for quite a while.

Have removed USB hub - didn't make any improvement
Changed power supply - no improvement.
Have changed SD cards - slight improvement, occasion mmc error in logs dissappeared.
Run without movie database - no improvement.
Removed overclocking - no improvement.
Increased overclocking - no improvement.
Increase memory setting - no improvement.
Tryed different FIQ settings - no improvement
Turned off CEC - good improvement.
Add/remove MPEG/vc1 codec - no improvement.

Last message in logs is usually "WARNING: CRenderManager::WaitForBuffer - timeout waiting for buffer"

Usually the Pi becomes unresponsive and extremely slow over SSH connection. Most of the time it locks and needs to be power cycled. Sometimes it will automatically reboot and occassionally it will start up again 15m to several hours later.

I have 256Mb Pi connected to a Pioneer VSX923 Amp for audio decoding (pass through) and then to a Panasonic TV.

Regards Phil.
