Two issues with avidemux

[alphadec]

Demo:
Fast Edit with Copy Mode enable caption with this one (youtube video)
Avidemux Demo, fast forward in 720p 5 1/2 hour video

It is important when editing in copy mode you select cutting point only with:
- Go to next keyframe or keyboard up arrow
- Go to previous intra frame (keyframe) or keyboard down arrow

I have now made a new thread with this issue with a *.ts file included (1gb) (dropbox) so have a look at this.

When I edit I am using the keys up/down ctrl+x, etc.
