DVD-9 to DVD-5 alternate method?

[onerag9]

When trying to rip a DVD-9 to a DVD-5, it is often necessary to transcode the video stream in an effort to shrink the filesize. You can then remux the new video stream and the audio using IfoEdit.
But is it possible to re-encode the AUDIO stream instead, and then use IfoEdit to remux? Changing WAV audio to MP3 audio would greatly reduce the filesize.
I saw that someone had done this with just the main movie file, then authored using SpruceUp. But i'd like to figure out a way to do it using IfoEdit and still keeping all original menus and extras and such. Has anyone tried this?

I personally think it is better to have the best quality audio and slightly lower quality video - especially if re-encoded with CCE. Sometimes difficult to tell the video has been shrunk but much easier to tell if the audio has been shagged with!!

Hi,
I would agree to rempeg the video stream, audio would probably not give you the space you wanted.
Another issue is the problem I have with dvd-audio:
I author self-made movies using spruce-up, i CAN NOT import mpegs with audio OTHER THAN 48khz MP2 audio !
So mp3 is absolutely NOT working on a DVD.

But this is my experience, maybe others found a way to do this

rinkel,

I'm still fairly new to DVD burning / authoring, but I thought DVD audio was always 48Khz and CD audio was 44Khz, or am I missing something here ??

Yes, you're right.
But i bought the program PowerVCR3, that stupid program encodes the audio at 44khz, so i had to resample it, i thought that resampling to mp3 would do the trick, but it didn't. I had to resample it to mp2 again... that's how stupid i am ;)

So anyways, resampling the audio would not give you a lot of extra space, resampling the video does, but that takes a lot of time.
I have succesfully resampled the video several times now with reMpeg. It's not very difficult, but it takes about 12 hours to do the job.
Make sure you have the right percentage, because otherwise you will have to do it again when it is still too big
