By request, I endeavored to work out a smaller file for my screencast. After numerous attempts, I produced an acceptable Flash file that weighs in at 17 MB. I had no luck compressing the audio to mp3 in Camtasia (final video would play without audio) and the other PCM compression option proved unacceptable. So the sound is uncompressed, but the change in video format makes a huge difference. I hope that this compels some of the bandwidth wary to take a look. And again, apologies to the podcast feeders. (The Flash file is not handled as an enclosure, so it will not download automatically. In fact, if you want to download the file, you'll have to right click and "Save Link as..." or whatever is comparable in your context menu.)
