Hi,

I've tried to transcode a recording recently (usually I don't keep
anything for more then a few days, so I don't care that much about the
space) and mythtranscode failed. I tried to start it manually, but it
bails out with:

I tried various tricks:
- Including -m in the command line - pretends to to something but then
quietly exists without actualy doing anything (after about 5-7min)
- updating transcoders settings:
update recordingprofiles set videocodec = "MPEG-2" where name = "MPEG2";

How do i fix this?
