Thank you! My Plextor ConvertX captures analog to digital and sends it to the computer via a USB port resulting in a .mpg file. Once my Intervideo WinDVD Creator (current very limited capture and editing program) edits it, it becomes a .wcp file.
For some reason, none of my files was currently available to the WinDVD program. (I had to crash and rebuild my HD recently, and that may be at play. Perhaps I have to re-register with Intervideo; I don’t know.)
I like it that your reply came to my e-mail inbox as I may have had trouble navigating back to the proper place in the very large forum. Again, thanks for your help.
A related issue is whether my current processor will handle the Vegas editing anyway. Vegas calls for 800 MgHz minimum and mine is 650. I don’t mind waiting for rendering and perhaps the speed was necessary for capturing via the firewire. I may need a whole new computer, or can I “get by” with my slower processor and editing pre-captured .mpg files?
