Actually, I had completely forgotten about the issue until you brought
it up.  I have had that in my crontab for many months.  I have not
tried taking it out of my crontab to see if I am actually still having
the problem.  I guess I should.....  But only when nothing critical is
scheduled to record ;-)

I assumed the problem had to do with the version of ffmpeg myth was
using when it first started happening.  I did not create a ticket,
because I knew that a new ffmpeg synce was scheduled before 0.22 was
to be released.  I am guessing by your email, that the new ffmpeg sync
did not fix the problem.

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
