Thanks, for the info, updating my burner, bye 
Thanks for the heads up masotime :). Off to check it out…
Thank you!
Something new to play with it 
This is what happens when I try to flash
BENQ DVD DD DW1640 Current firmware : BSHB
==> New firmware Version : BSIB
Linear CheckSum : 5188
Rotated CheckSum : 6CA0
Check Sum match !!
This Model is not support.
On Command Fail !!
hé, I cant download it from the benq-site, does anyone have a mirror?
Download link at BenQ Global not working right now. (07/05/2005 8:45 GMT)
Check out BenQ Europe (Germany) 1640 f/w page
Edit. Beaten by Quikee with a minute… 
My guess is they have pulled the firmware because it doesn’t work 
Maybe the screwed up the flasher =)
I have the same problem too :o
My flash worked!
Went from BSHB to new one.
Have an “original” BenQ, no OEM.
Glad yours worked. Mines a retail version also, so it’s nothing to do with that
You could be right! 
Just for comparison:
Media YUDEN000T02
Both burned at 8x from the same batch, also i tested the media from this batch
before with the plex, LG and the 1620, no problems!
The 1st one burned with BSHB
2nd one with BSIB ( It looks not nice to me, i’d flash back )
how are the write strategies? quality?
(answered before i posted … should’ve typed faster ;))
Looks like the PI is a bit lower, jitter a bit better, but still, PIF seems to mountain :S How strange !
Here is the MID list. The +RW speeds are probably not displayed correctly. The next MSCE version will support BSIB.
