I ordered the famous riteck GO4 after going through a 5 pack of Sony's. Still get the freezing at the end. I updated the aspi, DMA is on, using DVDcloner2 then tried DVD Shrink. The movie plays great until the end. I tried Bad Boys 2. Had the percentage to 77% and it was 4463 mb. DVD burner is a brand new Sony 530UL. could the PC be my problem? Its a Sony AMD 1.0Ghz, 256MB Ram, plenty of hard drive space. I do have a Dell laptop that is P4 1.7 Ghz, 128MB Ram and about 37gig free hard drive space. I have burned on this computer using DVDcloner2 with both Sony and Ritek DVDs with the same outcome...........freezing. Any thoughts? I have read this forum and tried everything I could find (aspi, DMA, media). Please help. The copies are great until the end. Even when using DVD Shrink, when looking on the back side of the DVD, it is not writing anywhere the edge of the disk; probably 3/8 to 1/2 of an inch from the edge. I am stumped.
