I never seen a DVR-533 in real life nor do I claim to know how it performs in real life.
I can however make two observations with almost certainty.
1) The Pioneer DVR-533, a way-back stand-alone recorder from 2005 has been tested with 1x to 16x media – more than one brand. The firmware will recognize 1x to 16x media and slow down the burn speed to the appropriate speed/strategy.
No one can tell me that Pioneer wrote in the manual…
“”“The table below shows 16x DVD-R disc brands that have been tested for high-speed writing compatibility with this recorder.”””
…without actually testing the discs and writing the speed/power strategy into the firmware.
They did this again with the Sony burner in the 640 and again with the 550 and Sony did it again in April 2008 with the 780. And it should be clear that with the Sony I’m not going by specs alone – I’m going with A) my personal experience B) The experience of many others using their 640 and newer decks and C) what my contact at Sony said.
2) The Pioneer DVR-533 has a laser powerful enough to burn at up to 12x speed. If the controller board can only handle a 6x speed – that burner burning at 6x speed should last for years burning 16x discs at 6x speed. Usually when you use something under-spec it lasts longer. Oh, don’t forget the 12x spec is only for a small part of the burn – not the whole disc.
Seems that it lasted for over 8 yrs for the thread starter and most likely “HDD ERR” means something could be wrong with the HDD and the laser diode could still be good.
I’m not telling anyone not to take Citibear’s advice to try 8x Verbatim AZO or T-Y discs if they have problems burning other media. I am however telling everyone that you will not hurt or prematurely wear out your laser by using 1x to 16x Verbatim AZO discs in a stand-alone deck that has a firmware strategy for burning such discs. That’s any Pioneer since the 2005 DVR-533 including all newer Pioneer decks and of course the 2008 Sony 780. The new available Magnavox decks as well. Although the maggies can’t burn DL discs – you will not hurt your new Magnavox by burning Verbatim AZO or T-Y 16x media.
Heck I bet the Funai firmware testers concentrate on the 16x media when writing the firmware – most likely they don’t even check it with 8x media anymore. Why would they when 99 percent of users will stick with the widely available 1x to 16x stuff in it???
It is a known fact that T-Y discs tend to be a little sticky and may not slip after other media starts to slip. I am not convinced that this is a good thing that is why I recommend a spindle cleaning when Verb AZO discs start to slip.

Good to know and as I suspected, Pioneer most likely crippled the +R capability in the 533 firmware just as Sony crippled the RAM-Write capability in the Sony 780 firmware. You can do a lot with firmware but I think DL burning takes a hardware update as the laser has to re-focus the angle to penetrate the second layer.
Oh and let’s face it CitiBear, if you and I didn’t have these

friendly

back-n-fourth discussions this DVDr forum would be dead, other than the few Magnavox posts.
That’s why I’m starting a new thread called.
Does Taiyo Yuden & Verbatim really use different dyes for their 1x to 8x blanks?
