I appreciate your time and help.
After much more reading here it appears until a better firmware for the 1650 comes along I will stick with the 1640 with my huge stock of TYG02.
I guess everyone was hoping the 1650 would upgrade the 1640.
I should know better with many years of experience with electronics.(home audio / video)
rbrtpl, your scan looks like my scans, a high PIE if compared to scans of the 1640 (BSLB) as zebadee stated seems to be the norm.
chas0039, I must say I'm sorry for your experiences with TY -R. I have used them almost exclusively since I started with my Plextor 708A. Even with my Plex716A and the Benq 1640 they provide excellent writes.
That's what was confusing me with the Benq 1650. The very high PIEs compared to the 1640.
I buy from Rima so I think I can trust their product. I haven't used +R media but if I stick with Benq I may have to experiment.
I thought SolidBurn was on by default.
Anyway, I remember when newer meant better. Guess those days are gone. (in some cases)
My thanks and best for the help guys.
