253173 2004-07-18 02:11:00 A techie in a computer shop told me that Ricoh DVDs are better quality than Princo. Maybe true, maybe not.... buit it made me wonder if there are independent tests / a web site - that has actually results of DVD quality?

In another thread here on PF1, the following web site:
www.cdmediaworld.com
....gives CD quality, but not for DVDs.

Anyone know?

Thanks - Steve

253176 2004-07-18 21:00:00 I went to another store and they told me the opposite . Princo better than Ricoh .

I have tried both .

Bought 10 blank Ricoh ($3 each) . Tried 3, 3 failed .

Bought 50 Princo (now $1 each) . Tried 50, 3 failed .

Nothing scientific about my research . It might be that my writer (pioneer) doesnt like Ricoh or might even be the software (nero) but my choice:

Princo .

Thanks Sam. I wonder if other users have such a failure rate? I have used my DVD burner only once on a DVD-R with Ghost and got a failed integrity check so thought I did something wrong but maybe it is a bad DVD disk. The DVD+RW's that I have used work fine.

What is going on with DVDs? The industry states that discs should last 50 to 100 years, but on-line reports claim significant problems with both pressed and recordable discs. Can movie discs wear out and fail from "DVD rot?" Is recordable DVD a trustworthy archival media, or is there evidence that discs can wear out from extended play? And what is the situation with the compatibility of recordable media? Is there a way to guarantee reasonable compatibility, some magic combination of formats and brands, software and burners, content and players?

www.dvdtoday.com

Includes testing of DVD players. Lots of info here, but still not sure what brand or type of disk is better.

If you think your prized collection of DVD movies will last a lifetime, think again - some are already starting to rot while others are falling apart .

Unofficial estimates put the number of affected discs at between one and 10 per cent . Yet some of the largest distributors for Hollywood Studios are accused of refusing to accept the problem exists and replace faulty products .

The failures are a combination of corrosion - known as "DVD rot" - and delamination, where the layers of the disc separate .

Symptoms of the rot include picture break-up and freezing at a specific place on the disk . The main cause is believed to be poorly designed cases . Delamination shows up as a coffee-like stain that prevents the disc from playing .

Among those worst affected are video rental stores, which buy millions of DVDs per year . "Some stores have reported they only get two or three rentals from a DVD before it's unplayable," said Ross Walden, director of the Australian Video Retailers Association .

253182 2004-07-19 01:27:00 Believe it or not, recordable DVD media is a touchy subject for me... I use Verbatim DVD-R's... used to use Princo, but found too many problems with jitter errors, etc.

You will find that even when a writer reports a, "Successful Burn," if you used the CD/DVD Test in the Nero Toolkit, you will find poor reflectivity causing errors in the DVD.

There are times when i will throw out a DVD after testing due to these errors.
