I've tryed encoding a 90 min movie twice now & @ 60% complete its already at 801 mb (this was supposed to be a 800mb 1 cd encode)
what am i doing wrong?
Could it be because of the version of tmpg I'm using? 2.524.63.181??

Just like that, right?
I mean, you did a prediction, right?
What did you use? Manual calculations? CQMatic?
There are just too many reasons why a movie that we intend to fit in a CD80 ends up needing 2 CD80s.
One of them is leaving the CQ figure with something like 80, that is, by not predicting.
So can you please elaborate a bit more on what you did?
Your tmpgenc's version is ok because it's the last one having been released before I gave up on tmpgenc.
I used it for many time without any issues.
Cheers

I used calcumatic to get an average bitrate
then created a tmpg project, then replaced tmpgs min bitrate with the avg bitrate givin by calcumatic & left max bitrate at daefault 2500.
then ran cqmatic & punched in movie time 90 min 40 sec & deep prediction & pressed full encode execute.
OVERSIZED FILE BY ABOUT 500MB

And why in the name of Jesus did you replace the 300kbit set for MINIMUM bitrate with the AVERAGE bitrate retrieved from Calcumatic?
Did you read that in any guide?
You need to let the encoder breath .
So, stick with the 300Kbit - or whatever low value your SAP needs - as minimum bitrate.
You put the average bitrate figure retrieved from Calcumatic in CQMatic's "Avg:" field.
Give it another run with these changes and see if it still oversizes by 00's of MB.
Cheers

The Untouchable,

My guide is an example for resolution 352X240 ONLY!!! It doesn't
cover every case. Also, I'm presently looking for a replacement of
DVD Decrypter.

I think I'm going to translate elora's french guide that covers almost all point form the installation and settings of the tools.
(don't ask when, it is very long and I don't have a lot of time)

For people reading french :
