Has anyone been using the CMC TY DVDs? TY was my gold standard. CMC not so much. So I wonder whether CMC has kept the TY quality up. Since TY exited the business, I have been using Verbatims, and they have been ok.
Unfortunately optical discs generally are falling out of favour and their future looks uncertain.
Only time will tell what CMC will do. If they adopt TY's technology and methodology, it should be business as usual but if they merely rebrand their existing technology then we are the poorer.
That being said, I have found CMC CD's to be very good regarding compatibility with unknown CD players. Somebody gave me a tub of Plasmon made CDs and they were bad. Ritek is another manufacturer that I have had mixed results with. I don't distribute DVDs or BDs so I have no experience on their compatibility. I generally use Verbatim DVDs and have only used Verbatim BDs with no complaints from me.
Unfortunately the manufacturer of a disc is not usually displayed on the packaging. It is only apparent using certain software. In the early days of DVDs Verbatim only made DVD+R discs, and their similarly packaged DVD-R discs were actually made by CMC. Verbatim now makes DVD-Rs as well (AFAIK).
I usually check disks I have burnt using Nero DiscSpeed and a LiteON burner to check the soft errors before error correction. This is a necessary test to pass but it is not sufficient to prove that a disc is generally compatible. Plasmon CDs may pass this test but still fail on some people's players.
Verbatim DVD+R all the way for me! They've been super-reliable. Haven't knowingly tried CMC though.
Verbatim for me too. But I did find some JVC badged CDRs that were TY.
"Haven't knowingly tried CMC though."
There-in lies the rub. My last spindle of Vebatim DVD-R was made by CMC.

I probably wouldn't have looked if I hadn't burned three coasters with DVD Architect 5.2.

Imgburn was able to burn a good one when I finally woke up (though not with the discs that are now coasters). I must be getting senile to let DVD Architect run hardware again after all these years of burning with a different application.
"My last spindle of Vebatim DVD-R was made by CMC."
See my earlier post. Can you use DVD+R? They are more likely to be genuine Verbatim.
I suppose I could and I will in the future.
