44.100hz to 48.000hz without losing quality?

I'm using TMPGEnc to convert from SVCD to DVD format, and while the picture is fine, the audio is significantly worse than it was before. If there any way to fix this? Thanks.

Have you already tried using ssrc (http://shibatch.sourceforge.net/) as an external resampling tool in TMPGEnc? (Option > environmental settings > external tool > sampling frequency convertor).

I downloaded and unzipped that program and there appears to be no actual prog in there, just a bunch of .dll's.

If this information helps, I tried to use DVD2AVI to produce a video and audio stream, then recode the video with TMPGEnc and multiplex in the audio afterwards. Unfortunately this makes it so it's not DVD compliant. Now what I'm trying is getting audio and video from DVD2AVI, putting the video and audio into TMPGEnc to convert to DVD, but changing the audio to the original's 224kbps instead of the DVD norm.

Find and download BeSweet (doom9.org should have it). That has evrything you need to up and down-sample mp2/ac3 files with pretty much "as good as it gets" quality.
(Besweet uses the SSRC engine that Freshman mentioned). There's also a GUI to go with it that makes it moderately straightforward to do the conversion.

Thanks. What I'm doing now is de-multiplexing it with TMPGEnc, then putting the audio and video files created from that together with the DVD template, only setting the audio to its original 224kbps. I did a small clip like this, and the sound was fine and SpruceUp accepted it as a valid file, so I think I've found my solution.

Hey VidGuy, I got BeSweet and the GUI, but do you think you could tell me how exactly I can change the audio? It's not very self-explanatory (the program) , at least not to me.

Mandrag,

I can't help you with BeSweet, but to answer your question about SSRC: The zip-file (ssrc-1.29.zip) DOES contain the actual prog which is called ssrc.exe (I've just checked again). Unzip this file to a folder on your harrddisk and make TMPGEnc point to it as described in my first post.

Perhaps what you did was to try and simply start this file by clicking on it. This won't work because it's a command line utility, i.e. you need to run it from a DOS box or use a GUI for it (in this case TMPGEnc).
