This post at No Fun Intended points to a $30 program you can use to record streaming webcasts. I require a tool like this because those webcasts are so insanely slow that I can not sit through them in real time. It drives me crazy. Instead, I download them and half watch them, rewinding when something interesting happens. ADD indeed.
I don't believe in paying for tools for things like this, luckily you don't have to. I've been using SDP (the Streaming Download Project) for about a year and it has (almost) never let me down. I highly recommend checking it out if you're ADD like me.
