Doh! why is my DVD-Burner acting so stupid?

Jul 12, 2001
when i try to burn a dvd with a directory called "Video_ts" it says the DVD is unburnable, but if i have the same information in another directory it burns fine, but then my stand-alone dvd player cant read it...

i am trying to burn with Veritas the software that came with my Sony Dru500
