I've been searching through this forum... awesome site btw.... to try and resolve an issue that I"m having with my Lite-On 451s.
Straight out of the box the drive came with a +R and a -R media and I tried burning video to both. The -R became a pretty purple-bottomed coaster and the +R burned with no problems (using DVD XCopy Express for both). I bought a 3-pack of Sony +Rs (4x OK) and they burned fine.... I've come to the early conclusion that the 451s prefers +R media and this seems to be verified by much of what I've read on this forum. Unfortunately, I just bought a stack of 4x-OK -R disks and am struggling with getting them to work.....
I hit two coasters about a third of the way into the burn with a write error. i then upgraded the firmware from GSB6 (thatit came with) to GSB7. The next -R I tried completed the burn but never finalized the disk. After a reboot the last one I did completed successfully but now neither my Sanyo set-top player nor my PS2 will read the disk (although both recognize the disk as a DVD movie). BTW, my DVD-ROM drive does play the movie using PowerDVD-XP so I assume the burn is good.
I guess my question(s) out of all of this is/are:
Does this mean that I've fixed it but less set-top systems recognize -R than +R?
Is there an older/more stable version of firmware that may give me a better shot of having myset-top system read the disk?
Should I just give up on the 451s as a multi-format burner and just stick to +R and be thankful that I got it at a reasonable price? And if so, does anyone want to buy 95 generic brand 4x DVD-Rs?
