Jolly good! At last we seem to be getting to the bottom of this.

You can actually adjust the pre-roll times using Video Studio.

1. From the Global Preferences select 'Select Device Control'

2. Make sure you have selected 'MS 1394 Device Control' from the drop down list, then click the 'Options' button.

3. Play about with the values in the dialogue. At a complete guess, given what you have described, I would try making the times longer. However that is a guess and it may take a few attempts to get it right!

Hope that finally solves the problem.

Good luck.
