I, too, get Procaster crashes on my macbook pro (core i5, 4GB ram) using v20.2 streaming at 600kbps off a DV cam through the ADVC 110. I currently have ticket open for it but I've been told to just reinstall it. I've had two live sessions I needed to stream and Procaster has crashed 4 times (no bandwidth issues or cpu overloads). A report window opens to send a report after the crash and I've sent at least one. If there are other ways I can help or info to provide, I'd be happy to.
