Hi Glenn,
You offer no background here - is this a new problem or is this your first video project? What version of VS are you using? Have you checked for viruses? If this is not your first project then what has changed since the last video project that worked and this one? The following advice is based on the assumption that this is your first VS project:
This kind of problem is not really amenable to any sane troubleshooting techniques - as an initial stab, I would suggest that you transfer your video files and project to another computer and see if the same problem exists there i.e. does the problem move with the video files or not? This would indicate whether the problem is with the computer or the video content (extremely unlikely it is with the video content - the major suspect is the computer).
Nobody else has reported a similar problem, so the assumption must be that there is
something (who knows what?

) on your computer that is causing the problem. The issue is how to isolate it and remove it?
A possible approach is to make a disk image of your computer (c: drive) using something like Norton Ghost or Image for Windows (later is shareware, so easier to trial). This will allow you to recover to your current point - it will also allow recovery of any personal data files that you may or may not have backed up somewhere - do not perform the next step unless you are certain you have a backup of all personal data from your computer! This advice is offered with all care but absolutely no responsibility

.
Format your hard drive and reload Windows XP (I assume you have XP) and any drivers required by your hardware. Then load VS 9 and your video project and try again (please note, do not load any other software - including software that came with your DVD burner!). If this works, then you could load each software package you own - making sure after each one that your video project still works OK. This might help you isolate the problem package. If you are using something like Norton Ghost or Image for Windows then "snapshot" your system at major (working

) points such that if you do isolate a problem package you can easily return to a working system.
