The other day, I was looking for a way to extract the audio from digital video - specifically, there are some video blogs - mostly interviews - that I'd like to listen to, but don't really want to be bothered with the video portion. Sure, I could put them up an iconify the video, but I do most of my podcast listening while jogging.
Anyway, Gary Short recommended Xilisoft Video Converter, which sells for about $20. I grabbed the demo, which allows you to convert up to five minutes worth. Seemed to work great, and the price is certainly right. I sure wish that amenable vlogs were available as both video and audio-only, but at least I can do that myself for stuff that looks interesting enough.
