The old Memorex discs that could be written in the past, did they have the same media code? This media code is usually tricky for burners to deal with as it's rare to see it supported by the firmware/burner.
Insert an old disc and switch to read mode and look in text of the right side of the progrram under disc info.
I should have checked this before.
You need a Blu-ray burner if you want to burn Blu-ray discs. This model is not one of those.

The time in length is of no special factor to determine if it fits or not. If you need to get it down in size to fit a single layer disc - use DVD Shrink or a similar application.
By inserting a previous burned (and working disc) in the drive and in ImgBurn look for this type of row.
For the previously burned ones, you should be able to see it if you enter the read mode and look in the right side of the program.
The other media code they used/use on Aone discs is this one.
When the burner tries to find the best writing strategy it is basing it on these media codes and not on the "brand" of the disc. Some media codes are better supported (not so likely to fail in the burn) by some burners compared to other burners.
Look at the threads marked Results & Discussion in this forum - you should see if the MID is working with a specific burner or not based on the posted disc scan graphs.

The MBIPG101-R10-65 Mid is a bit new and not all burner likes them, so they can be tricky. But if you burner struggles with true Verbatim discs, I would replace it. The cost of constant coaster should be quickly earned by a working burner.
These interfaces are just the "talking" between burner and OS and if the data burns with errors, it's internal in the burner there is something not right, like the firmware is not very good supported for certain Media IDs.
