What I've noticed is that it either works or it doesn't.  There's not 
stopping in mid-capture unless I try to play back the PPV in question. 
I've started verifying the oPCR setting and I'll be keeping track of 
them to see when it captures and doesn't capture.

I tried to capture again with the test-mpeg2 from libiec61883 0.1.0 
tarball and I ran into the same "File size limit exceeded" issue.  I'm 
now thinking it's not a filesystem issue but a header file definition 
setting the file size limit to 32 bits.  I did some digging around and I 
may need to enable largefile via a CFLAG option.
