Thanks John, great advice and I would say your knowledge and expertise has resolved this problem.
I was able to dig up an older DVD player from the basement. Tried 5 of the DVDs I had burned and it refused to recognize any of them! (worked great with a commercial DVD)
So as you say, it must be the media. I’m using HP DVD-R 8X discs, burning at 6x (lowest available option).
I’ll get better media, the ones you recommended from now on. In the meantime, I’ll tell the client to play it on a laptop/PC.
Thanks immensely for taking the time to help me out.
PS> we also share the love of music. I’d love to hear your music…do you have it online somewhere?
