[MEncoder-users] Broken mpeg files after EDL cutting

I am experiencing some problems using mencoder to cut mpeg files.
When cutting mpeg files recorded with GBPVR with my HVR-1600 card
I frequently (allways?) get the problem that the reported length
after cutting is 0:00:00. This occurs with the GBPVR viewer but
is reproducible with Windows Media Player. To exclude that this
problem stems from GBPVR or the HVR-1600 driver I build a "small"
testcase to reproduce the problem with a free mpeg from the web.
Get this file: <http://www.pangolin.com/images/video/creation.mpg>
Check that it is OK - Mplayer, GBPVR and Windows Media Player
play it, it has a length of about 4:40min and the slider works
in Windows Media Player to access every position in the file.
Now do this:
$ ./mencoder.exe creation.mpg -edl cut.edl -oac copy -ovc copy -of mpeg
- - - - - - -
0.0 260.0 0
265.0 280.0 0
- - - - - - -
and play it again.
The length is 0, and the slider does not work. Also mplayer plays it,
but shows a broken frame:
A: 3.2 V: 3.2 A-V: -0.002 ct: 0.111 91/ 91 5% 8% 0.4% 0 0
Broken frame at 0xB539
A: 3.4 V: 4.4 A-V: -0.997 ct: 0.088 127/127 3% 8% 0.3% 0 0
Interestingly this the broken frame is not there if mplayer uses the
original file and the EDL file ( mplayer.exe creation.mpg -edl cut.edl).
Is this a known problem? Do solutions exist?
