Ok, I finally figured out what part of the problem was. I noticed that
when I tried to mythcommflag from the frontend, it was running forever,
logging frames way past the actual filesize. It turned out that I had
been mounting the recordings directory on the frontend in /mnt/store and
the frontend tries that directory for direct file access before
streaming it from the backend. I was using samba and all the hdtv files
I was trying to playback were over the 2gig file limit. Whenever
playback got to the file size limit, it would wrap and start playing
from the beginning of the file again. I changed it to nfs today and was
able to finish watching a Joan of Arcadia that would always loop back to
the beginning about 35 minutes in. I will try it without the directory
mounted to see if it gets better. I noticed that I was able to get
playback to lockup a few times tonight when it was accessing the file
using /mnt/store directly.
