Im sorry for my bad english.
I started to search why mtn don't do thumbs for videos what have recorded from scrabled channels. I quess tswriter don't write movie duration to the file when using mdapi decoder. At least mtn says 24h duration for file:

\Team MediaPortal\MediaPortal\MovieThumbnailer>mtn.exe "\\mediasrv1\sharename$\tvrecords\Discovery Channel - 2012-08-21 - 22_00.ts"  -c 2 -r 2 -D 8 -B 500 -o .jpg -i -P -W -t

Audio: ac3
Video: mpeg2video, yuv420p, 720x576, 10000 kb/s, 25,00 fps(r)
  * scaling input * 720x576 => 1024x576 according to sample_aspect_ratio 64/45
  step: 17251 s; # tiles: 2x2, tile size: 512x288; total size: 1024x576
  all rows're skipped?

I run one file with projectx and it fixed 1429 out of sequence warnings/errors. Now it's showing duration to 10h, when it's should be around 1h. And now the ProjectX fixed something, that mtn will run thumb file. But it makes only 1 picture and while block next to it, because it's trying to get second picture from 4:25:14 what is out of endof file.

Is there any command line tool, to fix those ts files after recording, before mtn will run. Or better mdapi for newcs client.
