Another ProShow Gold Problem
I can only say that some time back Photodex made a small exe file available, for PSG users to check their burning hardware. I don't know if it's still available.
It was called "DVDTest.exe". You could check their web-site.
I'm trying to start using PSG myself, once more, as I lost all the files for several shows, which I had kept on a partition reserved for PSG work. I'm trying to convince myself it can't happen again.
It's a program with a lot going for it, but sadly there still appears to be a few hiccups.
