Some thoughts produced by IRC & myself.
To load inputed segment of movie into tasedit one shall greenzone the necessary frames by running || button. If you set input, but try to play it by simply advancing >, your input won't load. Exception is for FrameAdvance Hot Key, all hotkeys work as in normal recording.
This produces interesting effect of having different movies in TASEdit's memory at one time. It is like this picture:

You have greenzoned 100 frames of input. Then returned to frame 0 & redid some input. Greenzoned only 80 frames. Then redid input once again & greenzoned only 30 frames. If you now watch the result by advancing >, you will see 30 frames of newest movie, then 50 frames of older movie, then 20 frames of the oldest one. And by greenzoning them all ( || ) till 100th frame you will replace old movies' events by new movie, getting it normal.
So, speaking about
rerecord count, one shall add a counter to this cycle:
You edit input, then load it running || for the first time. This gives the first record, or 0 rerecord. All the next events like this will increase counter by 1.
A note for monitoring RAM while advancing >.
Memory Watch values advance according to a frame. But RAM Watch values freeze until you press your Frame Advance HotKey.
