[QUOTE=Albert;2759609]According to http://club.myce.com/f96/cd-dvd-speed-user-guide-192563/#post1540653 (if it doesn’t snap to the right post, it’s post #24, ctrl+F for “Offset”), CD-DVD Speed’s offset is read offset (for the drive, in this case the BenQ) + write offset (of whatever drive or device was responsible for burning the CD). It’s possible that CD-DVD Speed isn’t compensating for the offset on whatever made the CD, while EAC IS compensating by trying to use the database. [/QUOTE]
Albert , The Benq is the burning drive for the CD -RW .
I burned the “Test CD” that Nero CD-DVD Speed does just for the Advanced DAE Quality Test .
This CD is of course not the one I used in EAC .
I didn’t try to even open this CD in EAC .
I may give that a try but I thought is was just data on it for the test.
To clear any confusion.
In EAC I used the only one I have that I know works for the EAC test.
It is a commercial CD.
If you’re only concerned about reading, “618” is your number. If you’re concerned about whether the write offset of the BenQ is 138 or 66, I think using either EAC or CD-DVD Speed to create a test disc would help verify this. I’m inclined to think “66” is accurate unless it changed between firmware versions.[/QUOTE]
I agree read 618 & write 66 are what I decided to use .
There is other files & software I’ve done some checks on this that I didn’t post. They also seem to indicate those .
How ever what Drage posted is also interesting.
[QUOTE=DrageMester;2759610]I can’t answer your question, but according to my own tests the BenQ DW1655 (and thus almost certainly the DW1650) has a read offset of +618.
I have written down that the write offset is +138 for “slow burning speeds”, but unfortunately I haven’t recorded what I mean by “slow” (probably up to at least 16x) and what the write offset is for faster write speeds.[/QUOTE]
That may be information Nero CD-DVD Speed has .
If you add 618 + 138 you get 756 .
So I suppose it is possible that depending on the write speed either might be correct. Maybe +138 for up to 16 x & +66 for 16x & up.
