If I make it encode starting at 1:20 for 1 minute, the end of this encoding isn't necessarily exactly the beginning of the encoding that starts at 2:20. I supppose thet problem here is that Mplayer/Mencoder (I think) uses the information given by the AVI file to know where to start, but uses its own way to compute the time passed.

check -hr-edl-seek -edl

Also, wrap long lines, makes mails hard to read.
