How about I don't supply any more help? I, at least, offered an opinion. Doesn't mean it's right.

It's probably what I suspected before even opening the log. This goes a bit toward explaining it: I 19:54:52 Source Media Type: CD-R (Disc ID: 97m26s66f, CMC Magnetics Corp.) but it does not as readily explain why the Sony disc also failed. However, I have a feeling it's related. CMC Magnetics Corporation makes the absolutely worst discs out there. They are utter trash. You most likely bought the Verbatim Life Series CD-R from a brick and mortar store. The Life Series are junk. Now, Sony isn't as easily dismissed, but, over the past 23 years, Sony has also made little but junk. So, I'd be willing to wager their CD-R are just as much garbage as their BD-R's are. First thing I'd concentrate on is not using the trash media. Get yourself some Verbatim DataLife Plus (NOT the Life Series.) or AZO CD-R. Mitsubishi makes those. Those and Taiyo Yuden were the best out there for decades. Don't know about the state of TY's anymore after CMC Magnetics bought them. CMC Pro DVD-R media is still quality TY discs, though, last I used them.

I think the primary reason flash drives will never be used as physical media for releasing movies is they can't be encrypted like an optical disc drive can. DVD's and Blu-Rays were created from the beginning with hardware encryption baked in. Flash drives came out before the idea to release movies on them. So, like CD's coming before DVD's, when the CD was first released, the idea of even being able to copy them was never conceived of. So, CD's weren't encrypted. Since flash drives had a use for general data before the idea of releasing them as movies was even a possibility, encrypting flash drives at the hardware level wasn't standardized. And even if hardware encryption were introduced, I'd think Hollywood would be deathly afraid to do it. Too easy to copy the contents as a DVD or Blu-Ray from flash drives to other media and, especially, uploaded everywhere. I believe the Sony PSP handheld console had movies released in something I think called the UMD format, which was basically a little flash drive with movies that only played on the PSP. But, that was the closest something like that ever came and that was a Sony proprietary format. I hope those DataLife BD-R DL work out for you! Unfortunately, the "logical" solution which should like it should work doesn't always. Reply back with your experiences with them. I'm curious to see if they're worth investing in. I've not gotten any due to the price, but I would have archive uses for them. I don't do BD movies, but I do lots of data archives to BD-R over the past decade.

I just priced DataLife Plus BD-R DL the other day as I was curious. From Amazon.com, they work out to $2.78 US per disc for 25 of them. Actually, I'm not that surprised no one else has chimed in on this thread. Optical disc burning is pretty much mostly a dead end right now. It's a niche market at best.

Oh, yeah, I didn't think of it in that way. If you have a DVD+R and you want to "convert" it to DVD-R, you can't physically transmute the DVD+R to DVD-R, but you can copy the DVD+R's contents to a DVD-R. Just insert the DVD+R into a drive, use ImgBurn's Read mode to read the DVD+R to an image file, and then use ImgBurn's Write mode to burn that image read in Read mode to a DVD-R.

I figured it might be used to drag and drop files into Build mode. Never thought it might also add the files to Write mode's queue.

Here's your most probable cause: I 13:31:18 Destination Media Type: CD-R (Disc ID: 97m26s66f, CMC Magnetics Corp.) You're probably using the Life Series Verbatim you find in brick and mortar stores. Those are the CMC garbage. CMC Magnetics Corporation makes the worst optical media out there. Unfortunately, they also OWN Verbatim. However, luckily enough, Verbatim does offer a higher quality CD-R and those are the ones you should be using. Look for the DataLife Plus series (NOT Life Series.) aka AZO discs, which you can generally only find in online stores. Those are some of the best out there, as they're actually made by Mitsubishi. Keep in mind, this is not a 100% guaranteed fix, but it is where I'd start first. I don't know why you included a log portion referencing BD-R operations, though...

Question as is in the Title. Thanks!

CMC has a track record of changing manufacturing processes and borking discs. At one point, DataLife Plus DVD-R from Verbatim stopped working with the LG WH16NS60. The solution was to stop using them and switch to CMC Pro discs. Yes, even something with CMC in its name CAN be high quality because CMC Pro discs are not made by CMC. CMC Pro discs are made by Taiyo Yuden, which was the other high quality manufacturer of optical media along with Mitsubishi. CMC Magnetics then bought out TY like they did with Verbatim. Eventually, a firmware update to the NS60 fixed the issue, just reinforcing CMC changed the manufacturing process of the DataLife Plus DVD-R as only a firmware update for the NS60 fixed it. As for tests over time, I went through hundreds of BD-R's burned more than 5 years old over the past few years. All of those were the old Verbatim blue and white branded surface discs burned by ImgBurn in an LG WH16NS60. Every single one I burned still had totally readable contents after 5 years since burn. They were put in one of those CD carrying cases that hold like 320 discs and just stored in the corner of the room where I keep the PC in.

All I can add is even if BD-R completes Write and Verify doesn't mean it's any good. Last year, I had an experience with BD-R from CMC. For a decade, Verbatim, owned by CMC, made a high quality BD-R that was branded with a blue and white Verbatim label. I only ever had 1 failure that was not down to a drive that needed replacing and that was oversight on my part. However, I discovered a cake stack of these BD-R I had last year were completing Writes and Verifies, but were partially and sometimes totally unreadable in less than a week! Thinking it was just a bad batch, I got another and those were fine. Thinking it was just a fluke, I got a 3rd batch and out of those, only 1 completed Write and Verify while all the others I tested did not complete Writes! It didn't matter if I used my ASUS or LG BD burner, the results were the same, meaning it was the media. So, CMC changed the quality of the branded Verbatim BD-R so they're junk now. The DataLife Plus BD-R from Verbatim appear to still be good, but you can only get those in inkjet printable variety. So, you're paying an unnecessary extra fee for something you probably won't use just to get quality media. DataLife Plus (aka AZO) was always Verbatim's high quality CD-R, DVD-/+R, DVD+RW, and DVD+R DL made by Mitsubishi. Everything else is Verbatim's Life Series which uses CMC junk, except for the branded Verbatim BD-R. They weren't labeled Life Series and don't appear to be "CMC" in that the DID is "VERBAT-IM-000" but they are typical Life Series trash quality.

You can't.

If it asks to place a layer break, then it can't be under 4 GB. Interesting that the LBA % asks for 100. Hm. That's some bizarre and apparently shoddy ISO if it is indeed 1.) under 4 GB and 2.) asking to place a layer break on DVD-5 contents. In Write mode, open the ISO for burning but don't write it to anything. Just select the one LBA option and see what happens at that point. If the Write operation sits there waiting for you to start it, then the ISO apparently loaded okay. If it did load okay, post a screen shot of ImgBurn in Write mode waiting for you to start burning after loading the ISO.

Burn it as you normally would an ISO to any # of layers disc. Unless the settings were changed otherwise, the only difference is ImgBurn will detect the smaller size being attempted to be burned to a disc larger than required and prompt you if you're certain you want to "underburn."

Yeah, looks like over 50%. But, that's a good baseline. Thanks for gathering that data for me!

What is the time penalty for enabling the verify as you write a BD-R option? Does it double the burn time?
