Downloaded the trial version . I can copy my DVDs if I use DVDRWs, but not DVDRs. Got XP, Liteon DVD+R/RW internal. Tried two different makes of DVDrs and RWs to "prove" it. If I put in a DVDr on prompt, it burns the copy( can see this on the DVD) but when I put it in to play it.....nada. If I repeat the process from square 1 and put in a DVDRW on prompt....no problem. Even Win Explore shows a negative. Any ideas would be much appreciated.
