I believe you are asking the wrong question. Nobody can say that there is something wrong with a brand when you try to burn so far out of specs. Buy any kind of logic, it is to be assumed there will be problems since the dye, the reflective layers are not guaranteed to be of the same quality in that far outer areas, as the rest of the disc, and then it may not just be that much space! I believe what you see there is that MC present you with a warning and the option to overburn and will commence writing, at all riscs, should you choose to do so. But since a disc is made of polycarbonate and other things, not rubber, it can't be stretched forever
.
The fact that you get an error it's not the fault of the disc, it's just there is not enough space anymore. I can't comment on MC burning abilities (maybe the devs will), but not all programs will burn unconditionally, some do have a limit even for overburning. Apparently MC will let you do whatever you tell it to.
Now to get to the bottom of this and work with facts. There is a simple way to find out how much you can burn on your fav Sony CD brand. Get
Nero Discspeed, check the 'Extra' menu and choose the Overburning test. That will simulate writing to your disc (without actually writing anything) and will return the last possible value that can be written on that brand, given your media and CD writer.
Then you will know for sure how much can you burn on it, overburning included. Some brands can be overburned more than then others; sometimes the writer is important too but not so much as the blanc media. Then there are the 80 min CD, the 90min CD and the 99 min CD! (which all can be further overburned with various degrees of success).
Note: This has been a fun trip down the memory lane. CDs... Geez!
