I am having a real bad problem copying films with my DVD writer. I have no problems doing a direct copy of an already copied film (copied dvd > copied dvd). But if I use DVD Strink or SmartRipper on my original films and then use Nero to burn the files into a VIDEO_TS folder, the dvd will not play on any standalone, but they will play on my PC when I click on the files. I noticed that if I put a DVD that plays ok into my DVD drive and right click it, it gives the option "Play with Power DVD" (which is the software which I use to play films with). But if I put a dvd that wont play on a standalone and right click the drive, it doesnt give that option. What am I doing wrong??? Also when I try using DVD X Copy XPress the software writes to the blank dvd and i can navigate through explorer and see all the files, but when I come to play it, an error message appears "invalid format". My DVD writer is a Matshita DVD-RAM sw-9581 I have tried multiple DVD media and I get the same problems.
