Another company, Digital Rebellion (http://www.digitalrebellion.com
) sells software that can repair the unplayable quicktime files you are left with when procaster quits unexpectedly or crashes.
The software costs $139. I'm running a MacBook pro with OSX 10.8.3. If you are going to be streaming files you know you will need recorded, make the investment, at least until LiveStream offers up a legitimate fix.
