[mythtv-users] Restarting mythtranscode? / Sensing mythtranscode busy?

[Asciimonster]

I unwittingly stopped a transcode in progress. Therefore I cannot use 
the cutpoints in nuvexport.

Is there a way to re-do the original transcode? And if not: Is there a 
way to detect a transcode in porgress. This would allow for the 
programming of a warning light, or even a programme that would shut down 
the machine when transcoding was done.

Greets,
