Well, this method processes 811 MB, then crashes:

That's the sync problem I mentioned, I think. I'll try another flavour:

ffmpeg -i "input.mpeg" -copyts  -vcodec copy -acodec copy "output - c.mkv"

Crashes at the same place :-(

I think it is some error in the transmitted stream that makes ffmpeg to 
fail. But that's a completely different issue than vidcutter.

Maybe some specific mail list for ffmpeg?

Yes, this one finished correctly, and, vidcutter is able to load it. Now 
I'll try to remove comercials.

I try to use the keyboard cursor, but it is slow: I'm used to 
ctrl-arrows moving the cursor more than using the arrow. Ie, arrow 
speed modifiers. If fact, moving the cursor with the mouse doesn't work 
right, because on release it jumps to a different point.

Letting the movie play advances faster than with the cursor.

Ok, cut points defined... let's convert.
I forgot to see if the cut points can be saved to a file :-?

[...]

Well, it's the only editor that could cope :-))


There is, however, a final problem: it took only one sound track, it 
ignored the second. Typically, movies in Spain come in Spanish and 
English, and I want to keep both languages, obviously. No editor does.

I understand vidcutter uses ffmpeg. If it wrote an ffmpeg script, I 
could adjust the options.

Time to go to their mail list or forum and ask ;-)
