No, after pasting the mythtranscode command it executes and drops right
back to the CLI immeditaly with no message.
The ffmpeg command line is below about the fifo error.

Nothing is created in the /tmp/fifodir_3839/ folder.

The video's I'm trying to encode where exported to nuv/sql files via
nuvexport on my v.016 install and imported into my v.018.1 install. They
playback fine but dont seam to export/encode via nuvexport. I dont know
about the video's I've captured via v.018.1 (I've been deleting them
cuase i've already seen/exported the shows previously on my v.016
install) but I'll try exporting/encoding one tommarow.
