Ahhh! I have all my video set to work on PS3 without transcoding. In fact, on an older version of PMS, these files play fine without any transcoding.
This is from my debug log just before the fail...
This is a very basic mp4, though it may have 5.1 AC3 sound. (Made with handbrake High profile.)

I have the latest ubuntu package installed.
(This video plays fine with other renderers, but not the PS3.)
Any suggestions would be appreciated. I haven't modified the PS3.conf. (Audio and pics play fine on PS3.)
