Bad Burns, Part Deux
 

I just received 13 DVDs in trade, and they came on Dyson blank media which is coded as Prodisc F01 DVD-Rs. Out of the 13, only 4 play on my DVD player, or on my PCs. I put all of these problem discs in my JVC DR-M10 DVD recorder at home and got "Unreadable Disc" for each. Then I put them in all 4 of my DVD drives at home and the computers acted as if the discs were blank. The DVD drive in my Dell PC at work also can't read it. Even DVD Decryptor says "Disc is empty". Yet there is clearly something written on the discs. DVDInfoPro says the disc is blank, and says the disc is "not a DVD-Video".
Below are the DVDInfoPro comments on this mess. (Bad disc followed by good disc).

Any idea what is going on?

Sounds like unfinalized discs or outright bad burns. Either way.

I was gonna say unfinalized disc also.

It probably is the way they were burned, or as stated above, unfinalized disc. ProdiscF01 media is really top notch. I've burnt literally hundreds of them with almost no bad burns.

were they playing online games as they were burning them? It does happen lol

Actually they burnt 100% with dvd decryptor, no errors and finalized 100%.I tested handful of the spindle and they were perfect,then the rest burnt as stated so I assumed they were fine.However I just tested another Dyson dvd-r and it was a coaster after finishing.Then I burnt a memorex and an Ilo dvd-r both burnt pefect and played perfect.Now 5 years of burning and I have no clue as to why/how this happens sometimes.However I have bought spindles in the past that were either defective batches or my lite-on dvdrw burner found undesirable.I let jay know I'm buying a new batch from wally-world of Imations as my burner loves those and will send him replacements.I also emailed the seller I bought my blanks from and he's making things right on his end.I am one of the rare people who have had problems with prodisc media.Not sure why.And for the record lol nothing else was being done on my pc but burning.I have an AMD 3000+ with 2gb of ram,500 gb hd space,modded to the brim so my pc is fine.

Also wasn't too long back I had an entire spindle of Ritek coasters.Maybe it's my dvdrw?Might be time for another,perhaps the laser is crapping out or something,I don't know I'm just aggravated.

Burn some high grade media before assuming it's the drive. Get some "MADE IN JAPAN" media, from either Maxell, Sony or Fuji. Try to avoid Taiwanese media (with the exception of VERBATIM branded ones). See how that goes for you. Not to mention all of these are OFTEN on sale for about $20 per 50-pack, sometimes even a bit less.
