Looking for a great screen capture tool? I’ve got a new favorite for grabbing video on a Mac. Be sure to check out iShowU from shinywhitebox. This tool is much more stable then others I've tried and it is a true universal application that runs great on both Intel and PowerPC Macs. What’s truly unique is that the video files are captured and encoded in real time. This means as soon as the capture is stopped, the file is ready to use. You can create screen captures for web tutorials, DVDs, or even HD. What will all this power set you back? A whopping $20. Be sure to check it out.
