Well I have never noticed that before.
Looks like a bug to me. Certainly on the DVD I tested I had a 'First Play' video, and I suspect that Video Studio has got its numbering mixed up due to this. I will try later without a First Play clip and see if the problem disappears, or perhaps you can tell me if the problem occurred without a First Play clip.
Either way I will amuse myself with ULead support for a while (been ages since I have had a bit of fun).
COMPAQ something or other with 500Gb Boot Disk, 1Tb external Firewire Disk, 4Gb Memory and a super duper sound card, 19" TFT Monitor etc etc etc
