Josh, might be wise to see if you can transcode using ffmpeg on that 
recording and report back.  I've been reading mixed success using the 
internal 'transcode' option versus a user-defined script that does it.  
I personally have no problem with the internal ones I have setup, but at 
one point after an upgrade it just stopped working outright and it had 
something to do with settings for it in the database.  The problem for 
me was resolved by going into the settings and just clicking through 
them again (no changes at all) and 'finishing' their setup and voila 
things worked again.

Curious, how long have you been running your setup?  I've been all the 
way back to 0.17 or something, and I'm sure through the various upgrade 
something has been forgotten/missed, hence the gremlins I had encountered.
