Record Comcast DVR Video to Powerbook
Recently I had to pull off a video that I recorded on my Comcast DVD, I found the following link to be very helpful:

The page mentions downloading the 'FireWire SDK 22' from Apple. Apple only has the 'FireWire SDK 26' version available. You need to search the Apple Support database to get the file.
I had no problems getting the Video onto my Powerbook computer. Once it got on the computer I had to convert it to mp4 format, as the default video format isn't supported by many applications. There's all sorts of Commercial Applications (ie Quicktime Plugins) that can do the conversion. I found that 'Handbreak' did the converstion fine, and its free!
