So it seems that I accidentally picked an atypical example; most of my
recordings are closer to either 3.8 GB/hr or 5.6 GB/hr.  Regardless,
though, there are some things that I'd be happy to keep around at a
rate closer to 1 GB/hr, and transcoding isn't doing anything now.

I did manage to find what I believe to be the right error log, and it
contained this information:

Can someone please help me to fix this?
