Hi again,
I think I found a bug, at least this didn't occur earlier. So this is my scenario:
- I record a TV-show with MS Windows Media Center Edition 2005 from DVB tuner.
- I convert this file with PowerCompress to wmv. At this point all of the metadata is present.
- I trim the file with the VideoSplitter and the resulting file lacks (or has wrong) file size and/or aspect ratio metadata.
- I tried manually (and successfully) changing the aspect ratio to 4:3 with this tool: http://forum.doom9.org/showthread.php?t=116761
So I guess this is some sort of metadata problem.
I checked with the WMP10 the files properties and the aspect ratio translates roughly from my language to: real (22:15), showing (4:3).
So my guess is that at some point this metadata (AspectX and AspectY I assume) gets lost leaving the 2.61:1 as aspect ratio, which is wrong for this video. Or maybe the player just calculates this when metadata is missing? I also noted that the audio and video compression data was missing.
I believe that the two different aspect ratios are necessary because in my understanding as in DVD format the DVB specification handles wide screen the same way; image size is actually the same, but widescreen is produced by stretching pixels when played.
I made two files available for comparison, the first one being the direct result of the conversion and the second one is trimmed with VideoSplitter, I just cut few seconds from the end.

You should see the difference at least with WMP10.
Hope this helps to resolve this problem.
