AVI itself has'nt notion of ASR (nor PAR and so on) different from 1:1, so
avimerge itself can't delete such informations.
Transcode *can* setup ASR parameter (as well as PAR, if useful) using
--export_asr (--export_par), but since such value isn't stored into AVI
header, but, if any, into MPEG4 ES (video) stream header, it's the video
player that, at playing time, should look at such private MPEG4 header then
adapt the displayed video frame accordingly.
All this process it's out of any standard that I know :), so maybe it works
with a player, maybe it doesn't work with another.

Well, not the only I guess ;)

The main problem is that we *seriously* lack developing time. *Seriously*.
