Mpeg2 -> DivX6??

Hi,
I'm attempting to convert an Mpeg2 video to DivX 6 using Virtual Dub. I have this really good video, yet the audio is horrible by comparison. It's a music video, so I want to use the mp3 I have and import that as it's audio stream. I already know how to convert the mp3 to a wav and line it up and such, but transcoding Mpeg2 video seems like such a hassle. I wish I could just do a Direct Stream Copy, but I don't have the Mpeg2 codec encoder needed to do it, nor would I know which one was initially used to make this video. So far my attempts have rendered it where the aspect ratio, thou saying it was 480x576, made it looked highly horizontally compressed compared to the original. Plus, any considerate motion in the video causes this kinda scan line effect.

So, anyone know of a simple forward guide to fixing this exact problem, or ideally how I could find out what Mpeg2 encoder I would need to Direct Stream Copy in Virtual Dub 1.6.1? If I can keep the video unchanged but change out the audio streams somehow, that would be the best, but probably the least possible.

Thanks

i suggest you use "virtualdubmod", or "virtualdub-mpeg" for the job instead, they actually support mpeg-2 input :)

check out the dtv-->xvid/divx guide at http://www.divx-digest.com :)

Actually, I am already using the Virtual Dub 1.6.1 Mpeg mod. Or else I obviously wouldn't have been able to even open the video, let alone attempt encoding it at all. My problem is everything after that:/

well, like i said in my previous post, check out the guides at http://www.divx-digest.com

or here http://www.divx-digest.com/articles/dtv2avi.html

but IMO this method is better http://www.divx-digest.com/articles/dvd2divx5_gordianknot.html

Well, After tinkering with this for a while and not so much following the guides, as taking the few tidbits that actually helped; I managed to transcode this without much noticable loss in quality and vastly improved the audio. The only solution to this, as far as I could figure out, was to completely resize the video using VirtualDub's filters to 640x480 and adding a deinterlace filter, as well, to get rid of those annoying scan lines. Amazingly it worked. The video looks good and isn't annoyingly Mpeg2 anymore. Trial and error is fun when it finally works. Thanks for directing me to some info, thou;)

for deinterlacing i'd use these avisynth filters:
tomsmocomp or greedyhma

and btw: DVX (http://www.planetdvb.net/dvx/) is a very useful tool for the job you just accomplished

This DVX, wouldn't happen to be better, in regards to decrypting, than DVD Decrypter 3.5.4.0, would it?

not really, dvd decrypter is known to be the best, with dvdfab decrypter right behind it. dvdfab will soon surpass decrypter though, as newer copy protections are implemented...
