Tried to turn from digicam from my Canon S1 ("PICVideo MJPEG", 30 fps, 640x480) to mpeg1 (not mpeg2). The result is video that is fore-shortened in the horizontal direction. People look thinner (not always bad) but wheels that should be circular are elliptical. The effect is not gross but noticeable. Ulead technical support only suggested installing patches (already have) and basically punted.
I have seen video on the web (from 7.0) so this appears to be a problem in all versions.

In my opinion this relates more to your viewer program and/or the settings.
Independent of your format (640x480) the resolution of 720x480 - NTSC, 720x576 - PAL) is expected.
If that is not fullfilled, the stand alone players as well as the software players have to recalculate your datea, what may be end in different results and often can be fixed with other settings.
This is not a Ulead problem.

Viewer program not at fault
Each viewer program has the same result, Microsoft's Media Player and Apple's Quicktime player. In contrast I can take the AVI, feed it to TMPGEnc and get an mpeg1 that preserves the proportions. This is strong evidence that the encoder (Ulead) is at fault.
Thanks to Quicktime it's easy to compare the videos since QT will run any number of viewers simultaneously, so one can line up the windows and see any differences. TMPGEnc AVI and mpeg1 windows line up perfectly, Ulead AVI and mpeg1 windows do no line up.
Anyone can repeat this test so try it and tell me what you see.

The constrained parameters bitstream of MPEG-1 limits video to 396 macroblocks of 101,376 pixels. Encoders therefore reduce the 704 pixel width of your MJPEG to 352 pixels. For this, they typically do a simple sampling of every other pixel (some may take the arithmetic mean). If you try a 640 pixel width, then you will end up with 320, not 352 pixels, IMHO.
Vertically, one of the fields is simply ignored and the other is repeated to take its place for the standard 240 (NTSC) or 288 place. As there is no interlacing, this is progressive.
That having been said 320 x 240 is a standard MPEG-1 format at 29.97 fps (not 30) but it is possible that some softwares will not recognise it. Playback is converted by the codec to 720 x 480i or 576i. Most decoders can handle only a limited number of constrained parameters.
My advice: capture at 704 x 480/576i, 29.97 fps, do all your editing, then encode to MPEG-1 using standard settings to 352 x 240/288p
