AVI2DVD with OPV - Control of max bitrate

[ADLANCAS]

I´ve put a thread in CCE area...
http://forum.doom9.org/showthread.php?s=&threadid=81296
, but unfortunately until now no comments was made :(

Well, problem is about maximum value reached by CCE with OPV mode.
Below is a ~copy from the old thread:
".. Parameter max Bitrate works like a "target", but normally CCE uses higher values when necessary.
I tried also to set DVD compliant parameter. It´s better but not enough. I notted lower levels of maximum bitrate. Unfortunatelly, sometimes higher values were also present.
I´d use this DVD compliant parameter if my source was D1, but with half-D1, image is padded.
My (bad) solution in this moment was to reduce max bitrate(8000) and choose a low limit of Q to avoid higher values."

Is there something in AVI2DVD and/or CCE (2.66.01.07) that can help me ?

Thanks,

Alexandre
