[mythtv-users] 0.27.1 stores wrong length in SD mpeg2 recordings

[Hika van den Hoven]

Hoi Discussion,

About a month ago a moved from 0.26 to 0.27 and then 0.27.1.
Since then I have a problem with my recordings. I only record SD with
a PVR350 and a PVR500, so hardware mpeg2 recorders.
Here some statistics from first 0.26
recorded from till shown length on playback
     18:35-20:20   1:44:59
     20:05-21:50   1:44:57
     18:35-20:20   1:44:59
and recent recordings
     19:00-20:45   1:31:32
     18:00-18:31   0:27:07
      9:04-10:15   1:04:03
As you see the shown length is 10 to 13% to short and also has nothing
to do with the show length, which often is about that much shorter,
but not for the fifth recording. (30 min)

I first noticed it because if I jumped back a little (I have left set
to jump back 10s and right to forward 1 min) I jumped forward one to
several minutes. Depending on how far I was in the recording and the
time since the last jump. If the recording comes at the end of the
shown length it plays on till the real end.
Also commercial flagging is screwed up by this.
If I transcode either inside to nuv or outside by way of dv back to
mpeg2 (I use kino to remove commercials. The resulting mpeg2 file is
half the size without noticeable quality loss) the problem is gone.

The problem exists only with recordings under 0.27/0.27.1.
