Hi all, after much reading i bought a liteone 451. I have shrink 3.1.4, record now dx. After i backed up two movies, neither would play in my sony standalone, but one would replay in the computer dvd, this was a liteon dvd-r, the other is a matco dvd-r. I have followed the guides from here to the letter. Is this a media problem or a sony problem? No errors or faults were reported at time of burning. Any help would be aprreciated as i dont want to keep making coasters.
