It may well be the duration entry in recordedmarkup. The entry with

is using mythtranscode, the other is with mythcommflag --rebuild. I use

Some themes show the duration of each recording in the 'Watch
Recordings' list (e.g. Steppes) but this is just the difference between
the start and end times of the recording. I ended up writing a script
that would trim the start and end according to the cutlist, update the
start and end times of the recording accordingly and also filter out any
data stream from the recording, leaving all audio, video and subtitle
stream untouched (as I understand it, this should directly using
'Recording profiles' but that never seemed to have any effect).
Depending on the channel and the amount of data streamed, the final file
is sometimes almost half the original size!
