I've been on MSP since MSP6 and have been on MSP7 for over a year now without a problem. The other day I lost the ability to capture thru firewire, I can still see the ATI TV in the capture window. When I try to change the Current Device to either MS 1394 Device Control or TI 1394 Device Control I get a message "Unable to open the specified device. Please check if your device is ready". The GL1 is on, the Hardware Manager sees the Canon Camcorder as an Imaging Device. I have the latest MSP7 upgrade SP2.1. And capture thru Firewire is attainable using other software.
