With that same tool you’ll also be able to determine bitrate (Kbps) framerate (fps) and resolution. You may want to jot those down.
Now for the experiment part. Windows Media Encoder 9 will produce videos with MS’s ISO MPEG-4 v1 codec (fourcc MP4S). This option is only available if you choose constant bitrate (CBR) encoding for the video.
WME 9 is downloadable here: http://www.microsoft.com/windows/windowsmedia/9series/encoder/default.aspx
Here’s a walkthrough. I assume you have your original mpg or avi ready. Start Windows Media Encoder. You’ll get the wizard. Pick convert a file. Select your file, then for “How do you want to distribute your contents” pick 'File Archive'. Click next a couple more times. UNCHECK “begin converting when i click finish”. Then click finish. Now click on properties. Sources pick what you want to include/exclude (video and/or audio). Now for the compression tab click on edit then click on new (under import/export). Type a name. Video should be CBR by default. Just pick ISO MPEG-4. Set your framerate at the bottom (depending on what your player supports). Then click on add and add a bitrate. You can use K and M to shorten (for example 400 K, or 10 M). Then set your audio format, video size, frame rate, buffer size, video smoothness, and keyframe interval to your own liking. Click apply, then click start encoding.
Other users have attempted similar experiments with Aiptek products, with mixed (or rather unreported) results. You can read about their work here
