Ok here's the deal - I voted that I am sitting naked on the fence well not exactly
You see, I have and still own a LDW-811S, and so far not a coaster and very satisfied, despite the high kprobes on some media. Recently I got a SOHW-1633 and I must say that I noticed a few changes:
The green flashing led instead of the steady red/orange
(I guess you can say I've been mis-led...... :D) Ok bad joke!
Very misleading, always exceptional KPROBE readings, even on CRAP media
and poorly burnt media. The 1633 always report good, when in reality the disc is bad, and the same disk not being playable on players.
I heavily rely on my 811S, because it is the most accurate.
Also the 1633 burns like CRAP. Despite giving excellent kprobes.
Here is an example:
RITEK R02, burnt on a 811S = decent kprobe scan (with the 811S), with excellent results.
RITEK R02 burnt on 1633 = LOUSY kprobe scan (with the 811S).
So clearly the 811S burns better quality CDs and DVDs
I would definately use the 1633 for burning data, making high speed backups, etc...... But will always use my 811S for burning DVD VIDEO.
Even with the OMNIPATCHER, the 1633 burns most media like ******* crap - yes the KPROBES are always within specs (below 280PI and 4 PIF).
If you are extremely fussy on burn quality, don't bother with LITEON, don't bother AT ALL - LITEON has the industry's WORST quality burns. If you are into VIDEO PRODUCTION and do lots of video DVDs and want the best possible quality and compatibility, get yourself a Plextor or get yourself a 811S, I've burnt over 500 DVDs with my 811S and it always gave me good results and good kprobes.
If the 811S was such a bad reader as some people here say, then I would ALWAYS get bad readings - however when I burn media on my 811S, its kprobe is very decent. If I burn media on the 1633 and read it in the 811S, it is horrible - this PROVES beyond a shadow of doubt the HORRID writing quality of the 1633.
