I'm new to this forum so great to be here.

I have been using AVS Video Editor 4 and have found I cannot do the following most basic of things. Am I doing anything wrong do you know? It seems like these are severe limitations on this programme, which is otherwise quite good for a non-professional:-

* Cannot copy a clip / duplicate it in the timeline
* Cannot slow down or speed up a clip without affecting the whole timeline
* Cannot edit video once music track is on, as the music track also cuts up!
* Cannot recombine cut clips

Any help or advice would be good - or can anyone recommend a programme that can definitely do these things.
