Liteon makes utter crap drives. Imagine a manufacturer that makes a DVD writer that does not write to the most widly available disk in a country. Liteon will not write to moser baer 4X -R dvd's, although it is the same disk / material / chemicals / manufacturing plant as the mitsubishi -R 4x disk which it will write to but you try to figure that one out. Not only that but they have huuuuge quality control issues. Sony uses liteon drives so same crap usually. Benq is phillips and is +R. -R format inherently has flaws which makes it hard to write at high speeds. Pioneer developed -R so makes the best writers that write decent -R disks even if the drives are slower. Overall maybe LG is the best. I have spent months wasting time, effort driving all over the place and ordering disks that costs more than the drive to get my liteon to work and after an year took it back to the shop. Just the thought of throwing away 8000rs made me hesitant but I should have thrown it out long ago. Samsung is improving with their new U model as it uses a new chipset than the older one which is as good as liteon
.... NEC seems to make the best drive, with LG/pioneer/benq following. Safest writer is th epioneer, I never heard of anyone having write problems with it but it is also the slowest drive among the group.
Sanyo/optowrite is the only one who makes chipsets that let you write 20-40% more data than the disk is capable of using compression but you need the same drive to read it back if you use higher compression rates. But some others also uses this chipsets like plextor. But optowrite drives itself is rather liteon quality without the fuzz.
IF possible, that is if you can get good quality +R disks then I would look for a drive that is +R friendly (IE developed by them, since the developers have better write strategies so _R developers write better to -R disks and +R to +R disks)... BenQ is great for +R and much better than most in -R too.
