I've been burning DVDs with Nero Express (came with drive). These DVD-Rs will play on my PSX2 and Sony DVD players but not my Apex AD-600A. Because this is Nero EXpress I can't seem to find a way to check/set if I'm burning in UDF 1.02 or UDF 1.05

The Apex is suppose to be able to read DVD-Rs. So I suspect/hope that this is it. I've tried making an image w/ IFOEdit and burning w/ DVD Decrypter but same result.

Q: Is there a setting somewhere I'm missing?

Q: How can I check a burnt DVD-R to see it it's UDF 1.02 or not?
