Where is the graph that shows the overspeed to 16X and time of burning was 6:13 Min?.

Hehe; Look for this one:The following is the stragest burning curve I have seen so far, what is your take on this one?. If you notice the drive does not go through dropping speed or buffer dropping during the whole burning time.

Disc:Verbatim DVD+R (16X) MID (MCC 004)
Burner:BenQ1640 w/BSLB f/w
OS:On, SB:Activated, WOPCisable
Burning speed approaching to full 16X
Burning time:5:37

It's because WOPC is disabled, and probably you had used SolidBurn on this media type before?

Although the WOPC was disable for this burning case, but this type curve is normal for the fastest burning media 16X when burned @16X and WOPC is disable. Look in to the following like:

Same brand of disc, same burner and the same setting but completely different burning curve with -R with much slower time.

Disc:Verbatim DVD-R (16X) MID (MCC 03RG20)
Burner:BenQ1640 w/BSLB f/w
OS:On, SB:Activated, WOPCisable
Burning speed approaching to full 16X
Burning time:5:59.

One question : How do I show the white line on the CDSpeed graph, the one which shows the writing speed curve?

on the right hand side, the lower-most checkbox - "Show Write Speed".

This Time I thought I should try burning "Cheapo Brand" without over speed and keeping WOPC On.

Disc:Great Quality DVD_R (8X) MID (OptoDisc 0R8 (000)
Burner:BenQ 1640 w/BSLB f/w
OS:Off, SB:Deactivated, WOPC enable
Burning speed approaching to full 8X
Burning time:8:59.

I think GQ is using low end Optodisc media. OC-Freak was able to get A Grade Optodisc 8x DVD±Rs to burn at 12x with solid burn and OS activated.

For myself, I haven't tried it.

Go5s burn faster at 8X than 12X! Surprise! LOL :lol:

OS:On, SB:Activated, WOPC Disable
Burning speed approaching to full 8X
Burning time:7:57.

Note: even though the OverSpeed is on (activated) but the disc (GQ Discc) failed to be burned over its rated speed. Also the Transfer Rate speed at the end appears be shaky, unstable and its speed drops at blow normal speed.

Like I said, I do not believe that brand is asking for A Grade media from Optodisc.

Maxell 8X -R. Oversped to 12X, no WOPC.
Burn time : 6m30s (Nero)

Disc:FujiFilm TY 02 DVD+R (8X)
Burner:BenQ1640 w/BSLB f/w
OS:On, SB:Activated, WOPC Disable
Burning speed approaching to full 12X
Burning time:5:56.

Can some explain what is going on here , the burned disc has passed CD Speed Quality Scan Test with %97 score and very low rate of PIE & PIF, then why on earth the same disc can't pass the "Transfer Rate " test and has some unreadable sector?.

BTW:the disc plays flawlessly in stand alond DVD player.

Does BenQ 1640 Stands Tall?.
