So yes, I respect that you're experiencing a problem but I think you are aiming your frustration incorrectly. I've been using the current version since day 1 and and often, it is not performing worse, in any way, than previous versions. If the error is in the mastering, it could be laid down on an entire die lot.ģ. It's rare but I've replaced discs multiple time (once as many as 5 times) until I got one that worked. If the error happens at the same point each time you try to rip the disc, the error is on the disc.Ģ. Scenario wrote:The error is almost always something like:ġ. This tells me that it's not the discs and it's not my drive. But now, I'm trying up to 3 copies of the same movie and the failure rates are consistently high. Like I said above, last month it was rare to see these errors, and usually a replacement disc would fix the problem. This only started happening with the current version of MakeMKV. But 8 out of 10 times those errors will still happen - often after an hour of ripping. So next, instead of backing up the whole disc, I'll usually try to find the main title and just rip it.

The error is almost always something like:Įrror 'Scsi error - MEDIUM ERROR:L-EC UNCORRECTABLE ERROR' occurred while reading '/BDMV/STREAM/00801.m2ts' at offset '241041408'

I'm using Mac Sierra 10.12.6 on a 5K iMac. We'll see how that goes, but I'm not hopeful. I wound up sending my 2nd brand new Pioneer Blu-ray drive back to Amazon and ordered a 3rd one (a more expensive Pioneer model). The app should handle these kinds of errors, by interpolation if necessary, when there are no visible defects on the disc and replacement after replacement disc yields the same failures. If a disc won't rip, but it will play on a player, then the fault lies within the MakeMKV app. MakeMKV's error-handling sucks in general. It doesn't really matter what kind of error shows up in the logs.
