[mythtv-users] Automatic converting HDTV to MPEG2

[Michael Tiller]

In one of the other posts on the mailing list somehow had a hack at the end
to update the file size information in the database.  I don't see that in
yours but it seems like it would be relevant, no?

I never got that hack to work in my scripts by the way.  I always got some
kind of syntax error on the last line.  I think it had to do with the fact
that it was trying to inline stdin stuff in the script.
