Have just added a file to this program for the first time and I have a window saying

Searching for last video frame, checking directdraw sample update completion status time = 1478 seconds...

which has been running now for (as you might have guessed) 1478 seconds, anyone any idea how long this will last, is it a one off test, have other programs running in the background which could be slowing this down, should it be run on its own for best results, cos im a slow typer we are now up to 1618 seconds
