I just noticed that I am able to advance to those later scenes using the Preview Disc, by using the right mouse button rather than the left. The backwards buttons respond differently depending on whether I use the right or left mouse buttons. In my professional opinion the “preview disc” feature was insufficiently tested by Sony. The simulated remote should not function differently depending on which mouse button is pressed.
Thanks for the link. Some of the steps which you describe, for me, need more description. Most people leave out description because they are familiar with the software, but someone not so familiar doesn’t read between the lines so to speak. I used to test software and a bug report had to be reproducible based entirely on what the tester stated and it was no easy task. Nothing can be assumed, such as the platform and software versions. Forums are great because with many people explaining the same thing, eventually enough description is produced.
Platform:
Windows XP 5.01.2600 (Service Pack 3)
DVD Architect Pro 4.5a (build 59)
Vegas Pro 8.0a (build 176)
