If you have 2 rows with different ids, then it looks like you somehow
inserted 2 rows.  Can you check to make sure that all other fields
on those 2 rows are equal (except status and comment)?

The 2 rows listed are also 10 ids apart which indicates that you did a
whole bunch of other inserts between the time the 2nd row was inserted
and when the first one was inserted.  Did you queue up a group of
transcode jobs or just that one?
