I have burned several of these as I had a super large project. MCC Dual Layer discs were a bit out of price range for what I wanted to spend having already backed up the original source files to these before making dvd video compliant ISOs. We all know they cleaned up their act for single layer media long ago but I couldn't find any posts about this dual layer media so thought I'd test it.
The modern Ritek G05-66 discs seem to be excellent. TRT tests showed successful burns with completely smooth curves as a successful TRT test will show, on both* layers. The discs are readable in my 'weak' DVD player that will refuse to read anything but a perfect disc properly. It has even skipped on some recent poorly burned in an older worn drive but readable enough to work in most drives MCC media, it's all about the quality of the burn.
The 'bad discs' were badly burned to begin with and that alerted me to a failing drive. The only exception to this I had for dvds was a recent verbatim dvd R Azo spindle. This the two sandwiched halves were coming apart from the beginning and could be pulled apart with very little force. It's been a one off (and most of its burns were coasters or ones that failed testing), so I would absolutely recommend a TRT test and full ScanDisc test to make sure your burn is good, whatever brand or factory you might use. Having burned so many verbatim spindles in my life, it seemed a literal one off.
Ritek G05 66 passed the ScanDisc test as well.
Burned in a nearly new ASUS blu ray burner drive.
The ISOs are backed up by other means but given that I have multiple friends that wanted physical copies of our events, these discs made the best financial sense.
I have quite a few of the Ritek F discs in my collection that also are good.
It seems they did clean up their act regarding dual layer media too, I was surprised by the performance of their dual layer media.
I know many here will advice MCC only for dual layer, but the source files got MCC media so it didn't make sense to pay the super high price of that media for copies I'm dishing out for others and myself (printable surface). Plus the ISOs are on the NAS which has its own backup schedule. Id say in this use case the discs absolutely have given value at under half the cost.
While I'm not sure as to their archival characteristics, as has been said here I've never had a correctly burned DVD that was properly stored degrade and the tests were successful over a decade on, including some older CMC discs.
Note they were stored in a temperate climate, with some of them spending a year in a tropical climate.
