Compatibility issues?



Hey, just a quick question,

A friend of mine burned a dvd which plays perfectly on tv through any dvd player I try it in. I decided I wanted to make a copy of this burned dvd, but my dvd burner won’t play it, and does not even recognize that there is a dvd in the tray.

I don’t know what brand of dvd burner the disk was created with, but my best guess is that it was a different brand of burner than I have (sony dvd rw dru-500a), and that these burn dvds differently?

Is this likely the problem? Is there any way around it?
