48 Khz --> 44.1 Khz... always out of synch?

[castellanos]

Hi there!
I've generated a few avi and mpeg files from DVD sources, and I had the experience, since my first mpeg, that the audio (in that case mp2) should be the same khz as the source: AC3 48 Khz --> mp2 48 Khz. and of course, the same case with on an mp4 conversion: AC3 48 Khz --> MP3 48 Khz.
The question is: Can I generate an mpeg or an avi, from a DVD source(AC3 48 Khz) with an mp2 or mp3 at 44.1 Khz, without having any synch problem?
There is a program: DVDx, that actually can do that automatically. So, the fact is there... How to do it if you use TMPGEnc or Dr. DivX?
Greetings! :D

EDIT: Moderators: I've made a mistake, please move this post to the audio encoding section.
Thanks!

"Moderators: please move this post to the audio ",
but after I answered this question to adding my point.
hahaaa......

I guess you can use virtualdub-mpeg2 open this dvd file,
and select auio,check "full processing mode ",
then open compression ,select mp3 codec,set to 48khz ,
after setting ,you select "file" menu and select "save wav",
assume it's "a.wav”.
open BESWEET software to change a.wav to a.mp2,it's very important!

then use tmpgenc's "mpegtool" combine your mpv and mp2 to *.mpg
finished!
that's all I know.
