In both cases, mythtranscode was unable to create the temporary file in 
which it planned to transcode.

It looks like you're running mythjobqueue as a user that doesn't have 
permissions on (at least some of) the /mythtv_storage*/recordings/ 
directories (meaning that mythtranscode then inherits the 
user/permissions of mythjobqueue).  This may also explain why some of 
the transcodes succeed--because some of those directories have more lax 
permissions.  You should check ownership of all your recordings to 
ensure they're correct (likely mythtv user) so that you don't have 
problems deleting them at some later date.

FWIW, I don't think the --user argument works for mythjobqueue, so you'd 
need some other way to start it as the right user.  I'm clueless on 
upstart, so I'll let someone else help you figure out how that's done.

And, BTW, thanks for helping figure this out.  Once it's figured out, 
perhaps we can get Ubuntu to start shipping a proper mythjobqueue start 
script (or at least get one on the wiki).
