did you do any framerate conversion? like 23,976 to 25? did you follow any guide?

[Jmandy]

No i did niot change the frame rate its allways 25.And i did not use any guides.This method taht i use iv use it many times and allways work but now there is something that i dont understand.
A and one other question-All programs that i found about audio,video sync works whit an WAV files-the question is i can keep the 6 chanel audio even in WAV?

[Jmandy]

A and thanks.You are very quik.for furst time i recieve a post emidiatly

Theoretically, you can put 6 channel AC3 inside a wav file, however most (all ?) authoring software will not be anle to interpret it. Is the sync out by the same amount all the way through, or does it gradually drift ?

If it is out by a constant amount, try adding a delay (+ or -) to the audio until it is correct. Some authoring programs can do this. If yours can't, I have had success with AC3 Delay Corrector.

Thanks for all man.I found the problem.It was ignorance,please scuse me that i take of yuor time.It was that the movie is about 3 hours and i want to make it in just 2200 MBcous usuali i make two movies on one DVD.But this one is big,and when i convert it whit TMPEGenc i lose the big part of the film.
Aniway thanks for all I will try the program.
And i have one more question how can i reduce the mpeg file size whithoud convert it.Becous only whit TMPEGenc i can put the file size but its a litle slower.Iprefer to use Mainconcept but this program make the files too beeger iven for normal DVD.And can you tel me about a program for authoring that works directli whit avi files.Normali i use DVD-lab pro(Its great program but takes too much time and space first to convert the avi in mpeg2).
All yours Jmandy
