I just tried to import media from a TV DVD. I followed the instructions as I saw on Youtube. and the file would not open. When I did it with a movie I recorderd with my VHS stabilizer the file went through.
I just tried to import media from a TV DVD .... You can't import media from copyrighted material?
What's a "TV DVD"?? You mean a commercial DVD release of a current, or past TV show?
Yes, there are copy protection measures that they install on such disks to prevent (or discourage) copying them ... and loading the file off the disk into Vegas is such a "copy"
HOWEVER ... your Subject refers to "screencapture" ...is all that you are trying to do is get still frames off that disk?
If so, there are DVD player software programs that will do that. Windows Media Player will not, but I've had programs in the past that, in addition to playing the DVD on my computer screen, will take "screencaptures" (still frames) from the movie disk. I don't have such a program now .. and I can't tell you which ones today will do that (if any) but that is an option for you to investigate if that is what you are trying to do.
