:lol: I see what you mean jjsevdt, I mis-understood first time round.
I have a cheap dvd player that has played everything in the past, mpeg, wmv, wma, jpeg etc.... and being a few years old it is dual layer.
I'll just have to find a dvd player that'll play these discs as I bought a job lot for a good price, but not good enough to try different discs!
Cheers though guys.
