[mythtv] new defer transcode feature also defers user jobs.

[wes white]

I have a user job (#3) set to run myth2ipod.
I have my "defer transcode" set at 1 day.
The myth2ipod jobs would also stay queued till the transcode ran. also  
meaning myth2ipod would convert the lower quality transcoded file.
The transcode had a schedruntime of "+1 day at midnight" and the  
myth2ipod had the time the job was added (end of program airing)

after a little looking into the database, i adjusted the inserttime on  
the transcode job 1 sec later.
my myth2ipod jobs then ran immediately, and the transcodes ran at the  
correct time. which is my understanding of how this should happen.

My guess is whatever part of the job queue that looks for the next  
job, is getting the 2 rows mixed up since they have the same chanid,  
starttime and inserttime but different schedruntime

I can by no means fix this myself, but hopefully someone who knows  
what they're doing can.

i have now written a little cron job / php script (may not be the best  
way, but it's what I know) that automatically adds 2 seconds to the  
inserttime  of the transcode if it finds duplicate  (chanid, starttime  
and inserttime) records
my myth2ipod jobs now run as soon as they can, while the transcodes  
are put off till the next day.
