This is 32-bit.
These are on videos that were working fine last week, and now they have this problem. I wonder if it has something to do with the sound driver, as I noticed if the machine is left on for several days the sound sometimes will skip constantly, and I have to reboot the core. When I first built the system it didn't have this problem (that I am aware of).
I'll check those logs, any other ideas if that doesn't bear fruit?
