Hello!
I'm thinking of buying a DVD+/-RW drive and I don't know what drive to choose:
Plextor drives are too expensive for me.
LG - a month after the guarantee period is over and...
Sony - after the buggy CRX320E (http://forum.rpc1.org/viewtopic.php?t=36622&sid=009ba00a713858c57e92dd1a83fb0b2a) I don't wanna buy devices from this company (as well as TEAC, Lite-On & Co
Another thing is NEC, or PIONEER, or BENQ. The price is fine, but the features... I just don't know.
Nec (as I've read on the other forums) seems to have bad error correction,
about BenQ also there are a lot of different opinions, the Pioneer's reputation seems to be more clear.

So, my requirements to the drive:
1) The drive reads/writes everything with good quality (of course
2) The drive has a good error correction and PERFECT DAE quality, even from old discs.
3) The REAL reading speed (not NOMINAL) has no matter for me (as well as the REAL writing speed), the QUALITY is the matter.
4) Of course, I'm watching for a modern drive: 16x DVD+/-R | 8x DVD+RW | 6x DVD-RW | 32x CD-RW | 52x(48x) CD-R ||| 16x DVD | 52x(48x) CD.

Does Pioneer DVR-110 suite these requirements? Or NEC ND-4550A? Or BenQ DW-1640?

P.S. About the Pioneer's drive: I've read on the other forums that the Pioneer's reading speed cannot be changed by third-party programs (like Nero DriveSpeed), is this right? It has a great matter!

the BENQ or the Pioneer is a nice writer, the pioneer 110 doesn't have a riplock on it, so speed increase isn't a problem, they both can be made rpc1 and have there media ids changed. Your never going to get a dvd writer that is a perfect reader though and the 52x for cdr isn't an option any of these have either

Do you mean that I CAN use Nero DriveSpeed or an equivalent program to change the Pioneer's read speed to a LOWER value, for example to 8x, or 4x?

Or maybe I have to flash the drive to the XT version and then and only then use the Pioneer's official software (like the Plextor's PlexTools)? But not third-party software?
