Microsoft MPEG 4 V3, 40 fps problem

[Cryophallion]

So, I believe I have a singular problem. I Screen-capped (using camstudio) a work related webcast. During the testing phase before the capture, I tried all the codecs available, and found mpeg-4 v3 to have the fastest framerate and compression ratio. I jumped the framerate to 40, as that gave me the best input framerate (note that it compressed to avi)
Now I want to edit down and recompress the video. As we all know, Vdub doesn't play well with microsoft. So I can't use that.
Tried tpgmpeg. Video and colors got all screwed up.
Tried framerate hq. It crashed just like vdub.
tried vdub 1.3 on a rumor. It crashed.
Used Premiere Pro 1.5, but the video became choppy, and there are no good framerate converters for it I am aware of.

I think I've tried everything I have heard of. Anyone out there that can help?

Use another codec.

The last time I used CamStudio, I captured to Lagarith (lossless) codec. It was fast, the video quality was perfect and is easily editable in Virtualdub or Premiere.

Just tried it for future reference in case this comes up again.
Lagarith only gave me 12 fps input.
v3 gave me 19 to 20.

As this is a one time thing, max framerate is important (hence the reason I used v3 in the first place)

Also, lossless uses up a ton of hard drive space. When we are talking about 2 - 3 hours of capturing, I would prefer smaller file sizes.

Thanks for the input though.

Anyone on the existing problem?

Another quick note. If I could, I would go back and use another codec. However, the damage is already done. The video was a one shot unfortunately. So I have no choice but to contend with the above problem.

I'm not familiar with the format you used, but I've never found anythng that AviSynth can't tackle.

MS MPEG-4 V3 = DivX3.11alpha. Just has a fourCC of MP43 instead of DIV3. ffdshow supports decoding both.
