755 Review (by HWP)

Those discs may be manufactured by different companies. Maybe you have a bad batch of discs.

True, they are Made in India, but 4.1 instead of 0.41 average (practically)???

But anyway thanks again Arrow, hwp and others for - like so many times - helping me out again!

I have too many questions I know...

Several scans merged to the Post your Plextor 755 DVD quality scans here thread. This is an ongoing review by hwp so please post your scans in the appropriate thread and not this review thread. Thanks.

Verbatim 700MB 32x US+RW (Mitsubishi Chemicals Type 5)
PX-755a, FW 1.05
Burn speed 24x Z-CLV

Not really encouraging results. But at least no CU errors.

Scan 1: new media, C1/C2-scan after first burn
Scan 2: C1/C2-scan after 3rd burn
Scan 3: C1/C2-scan after 5th burn

A full erase was done after each writing.

Taiyo Yuden -R 16x (TYG03) sold as Panasonic
PX-755a, FW 1.06
AS: Auto (did create strategy)
Burn speed 16x CAV

One big PIF spike @2.9GB position for no apparent reason (regular Beta at that point, no PoweRec reclibraton, etc...). Earlier firmware showed a similar result http://club.cdfreaks.com/showpost.ph...&postcount=112 but then there was a change in speed at that point, which is not the case here.

TDK -R 16x (TTH02)

You'll perhaps remember the failed burn as shown here
http://club.cdfreaks.com/showpost.ph...&postcount=161

It seems the lot of TDK -R media i have is of very variable quality. While this one used in the PX-760 review http://club.cdfreaks.com/showpost.ph...&postcount=127 was a good one, the one used for the PX-755 review and the one shown below were very bad.
