Graphedit trim filter. Exist?

[magilvia]

I need to trim exactly one GOP (which is corrupted) from an MPG file whitout reencoding (for importing in DVD Maestro), but I noticed that many programs which claims to cut MPG cause often "GOP out of sequence errors" while importing or are not frame-precise while cutting.
So If would exist a graphedit filter to trim file source it would be easy to cut files. I searched all over this forum and the net but found nothing.
Any help will be much appreciated :)

I've tryed mpeg-vcr and works quite good. Anyway I still would like to have a trim filter which could be much useful. Thanks.

Mhhhhh I used mpeg-vcr with some files but It introduces many "GOP out of sequence" errors. :angry:
No one knows a trim filter ?
