FCE 4 Froze At The End Of VHS Capture Through DAC-100.

Question

I spent a large part of yesterday copying a 2 hour VHS tape to FCE 4 via my DAC-100.
At the end of the 2 hours I pressed the esc key only to hear a warning "thud" bleep and find that FCE had suddenly frozen.
After I force-quit I found the 25GB file was useless.
I tried again with a 30 minute capture with the same result.
During each attempted capture I had briefly answered an email.
Assuming that my short internet use had caused the end freeze I tried again, not using any other computer function and succeeded.
Whilst using the web is the chief suspect, could there be another obvious cause? (I am sure that in the past I have used the iMac whilst capturing).
The irritating thing was that it waited until the capture was finished before freezing!

Answer 1

That is interesting Armando.
Thanks to your info I can now use Spaces!
Here are the results:-
1. With FCE capturing in Window 1, I can switch to Window 2 and open Mail (or any other app), use it and go back to Window 1. (This works with both camera and converter captures).
The Mail name is still in the menu in Window 1 and I can't bring up FCE's name but it does not matter because pressing esc stops the capture and puts FCE's name back in the menu.
2. For it all to work, I must OPEN the new app in the new window. If the app is already open, even though I "wake" it up in Window 2, it will lock FCE when I go back to Window 1.
3. As mentioned previously, if FCE locks whilst capturing from a camera, I can simply manually stop the camera, FCE will unlock and I get the "End of Tape" message. The capture is successful. But this technique does not work when capturing with a converter.
So, you have shown me that I can use other apps whilst capturing by using Spaces, but it does not explain why I have the original problem.
I have just done some capture tests on my G4 eMac (OSX 10.4.10) and opening other apps during capture does not cause a problem.
