First off I have to say that DOSBox 0.65 is AMAZING. Great Job! I'm having a lot of fun with the video capture and after playing around with VirtualDub and TMPGEnc I can see why you settled on the format that you did. Which is why I was wondering what other peoples' thoughts were on CODEC, Software, and settings. Personally I'm trying to make a DVD out of VR Studio captures that recreates the Instructional VHS tape that came with the original software. I'm sticking to MPEG2 (haven't settled on a compressor application yet, I'll post here when I do) but I've noticed that DivX (ver 4 low-motion, ver 6 doesn't seem to accept the captured video) produces a file much larger than original (I could be doing something wrong. Anyone else have any success in compression the video down to something you could put on a website?

Just a quick note.. The Windows Media Encoder does a great job compressing the captured video in at least a semi sharable file. You can find the software at http://www.microsoft.com/windows/windowsmedia … er/default.mspx
I'm still experimenting with MPEG (I still get file sizes larger than the original format)

That's not very miraculous. IIRC, MPEG2 enforces a rather high percentage of keyframes (one in 18 for NTSC, one in 15 for PAL I believe). Also MPEG2 is tuned for natural images (soft edges, gradually changing colors etc.), it doesn't do all that well on typical computer graphics (sharp edges, few colors, straight lines etc.).
