Well, I am guessing something is broken. When I try it from the "Watch
Recordings" menu nothing happens. When I try it from the OSD menu, the OSD
diplays "Stopped Transcoding" and nothing happens. I've checked and
mythtranscode is installed and the mtd is running. Also, I created a "1080i"
transcoding profile per your description, but it doesn't show in my menu as
a choice when I go to transcode a show. What's wrong here?
Thanks in advance.
