Hrm.  That seems consistent.  Not so much.

Well, it seems that my MJPEG recordings are not being transcoded then.
I have a 20min recording that is 2,503,697,308 bytes, which while about
right for a 50% quality MJPEG recording, is much too big for my
RTjpeg/MPEG4 transcoding profile of 2000/2/15/3 (Bitrate/Maximum
quality/Minimum quality/Max quality difference between frames) settings.
Those exact same settings on my MPEG2->MPEG-4 transcodings are just a
hair under 1GB/hour.

So, any ideas why this is not transcoding?  Probably related to the
error message from mythtranscode:

Couldn't find stream paramters for '/video/tmp/1006_20051003230800_20051003233000.nuv'

But the stream seems fine in as much as it mythfrontend plays it without
problem.

Any more ideas?
