Hello,

Yesterday, I queued two HD shows to be transcoded using the High Quality
mpeg4 profile.  One show completed successfully, whereas the other show
erred out.  I checked the logs, and found some odd information, and was
wondering if anyone could look it over, and help troubleshoot the problem:

2012-04-19 03:46:00.805 Found video height of 1088.  This is unusual and
more than likely the video is actually 1080 so mythtranscode will treat it
as such.

/dev/video does not exist, and the bitrate I used for both shows was 4400
(I doubled the default of 2200).
