I really need to burn my dvd with speed x2. Is there any chances to do it? If yes, please tell me how to do this.
thx in advance!
can you tell us why you need to burn at X2 speed, is it the disc’s?, or do you prefer to burn at this speed
also what program are you using to burn with?
I need x2 cuz I’m trading concerts. And I bought this benq 
Nero shows x4 is lowest. nero toolkit shows the same. what program should I try?
If there’s no technical reason, you should burn media at its rated speed or one speed step lower…
Most newer burners are not optimised for low speed burning!
Set the drive to use PIO mode and Benq will probably be forced to burn at 2.4x?
OUCH, setting PIO mode will cause the buffer underrun to kick in and wreck a quality burn.
To get the best quality burns DON’T brun slowly. Get some good quality discs and burn at or 1 stop below its rated speed. Using cheap quality discs will give you poor quality burns no matter what speed you burn at.
The days of slow burning to get good qualty have long gone now high speed burners are around. With some media it can even make the quality worse.
I’m using only verbatim + and with x4 quality goes little worse. just a little, but still 
These DVDs are x16 max, so I’ll try with x12. thanks for fast responding!
yaa I burned with x12, and it really looks good. thanks 1 more time!!
i think the rated speed is the best
because the benq 165X only has the strategy of the rated speed
when you use another speed,the solid-burn fuction will work,and that’s what i don’t like…i don’t think the strategy made by the burner is any better than the one made by the BENQ factory
Not true…
The firmware for most drives have different speed settings for most discs, this is to allow for you to slow the burn speed down when neccesary.
The MCC004 disc is rated at 16x, it may well have a very good 16x burn stratagt but it also has 4x, 8x and 12x stratagys built into the firmware.
Here is a list of the firmware speeds for a DW1655 with BCDB firmware (only one I had to hand), note all the other speeds listed, these speeds are all built into the firmware.
