I compiled the patch into fixes 9163 last night. I tuned to an HD
station on the firewire waited for a few (what turned out to be major)
glitches and got,
2006-02-27 13:48:02.608 Firewire: total dropped packets 0

Downloading SVN (assume fixes won't have the applied commit in it?)
and will apply the patch.

I also noticed in the backend log:
2006-02-27 13:37:39.395 AutoExpire: Adding Programs to 'Do Not Expire' List
which I hope is only adding the shows that I marked as "Do Not Expire"
and not other shows!
