Theres is absolutely nothing wrong with Audiodevs testing procedures, but i have a mail discussion as prrof if you would like to read it with statement from Audiodev with statement clearly that a higher score does not necessarily mean the disc is more compatible or has better playback in the majority of end consumer units. But this testinstruments are very expesnsive and very accurately, the purpose of them however, is NOT to aid end-customers in their purchase of media. But to aid R&D for manufacturers. This debate i had with Audiodev .SE earlier this year also showed the Mitsui media (cdr) that had much better signal tracking and overall score then Smartbuy/Prodisc CDR media, however, the Smartbuy/Prodisc media had better becnchmark results on the "lesser quality" media in all tests on independent drives and had better compatibility with Car cd players. According to Audiodev this is/was not a surprisem, as theyre testing procedures are for the manufacturing business primarily, and test results show physical capabilities and raw quality of the media. It is not to be used as a guide for end-customers in their purchase of media, although they might find it helpful in many cases.
The fact that Princo media was banned affects alot of brands, whom have purchased their media through Princo factories, now they take the hit... without ever knowing Princo used TDK manufacture id on discs. I didnt say they were banned because they didnt pay royalties, all i have said all the time or/ meant, is that the problem is not the quality of the media, but the FW of the drive. Which you now more or less admits yourself, thats my point. Then , ofcourse the reasons could be argued about. The bottomline, however is that this means less happy customers. We already have had over nearly 100 cancellation on 105/A05 orders only where i work, due to this issue from customers who now choose to switch to the Sony DRU500 or the Nec 1100 instead. In the end, these moves by Pioneer will do them more harm then good. And you cant really argue with me when i say the A05/1045 produces bad quality on recorded media, since it has already been prooved that just as many discs that were not Princo manufactured shows the same symptoms, even "hi quality" branded media.
Also, my company is doing a real huge "real world test" which is more helpful for end customers then the Audiodev hi technical tests are. This test includes benchmarking on recorded DVD-R and DVD-RW medias in different types of readers. This will include Transfer rates and seek times made with different readers. The medias that will be compared with eachother are the some of the following:
Verbatim DVD-R, DVD-RW
Imation DVD-R, DVD-RW
TDK DVD-R, DVD-RW
Maxell DVD-R, DVD-RW
Whitelabel DVD-R, DVD-RW
Datawrite DVD-R, DVD-RW
Neo Premium DVD-R
Bulkpaq Greentop DVD-R
And many more. This real world test is more interesting for end customers, as it shows how many of the end consumers equipment will intercept, read and playback these different type of medias. Our purpose with this test is simply to show our customers some of the differences between the medias and theyre playback abilities on some of the most common DVD-Rom readers and players.
I can say already now, that Imation discs that are apparently rated very low had better results then some of the bigger brands, now there is a difference between Physical tests and real-world tests as we could clearly see, and i already have had confirmation from Audiodev that there is generally nothing strange about this. Also, due to the way different brands tunes their drives, physical test and measurements are again, not true to real-world usage.
I will post a link to this whole huge test once it has been done, it will be rather huge with graphical graphs for all medias, also due to its nature it will take a week more or so until its done.
