No, I am below 2GB. I know about this restriction, and I try to keep below
this Limit therefore, because some players crash otherwise. But you are right.
Normally I use some value like 1600-2000.

Can you, please, e-mail me encoding-tips.txt (rainer at hantsch.co.at) or leave
me a pointer to it?

?! Aehmm - You mean I start with doing the first pass ov video encoding
instead of extracting audio?
