Even if it handled all anti-copy schemes to perfection and had excellent handling of read errors and the like... it still requires a BD or DVD drive in the encoding computer, and to have the the BD or DVD in the drive, every time a new encode is needed.

That's highly inconvenient.

Makemkv only needs to run once. Afterwards, you can just deal with the file it creates, which is much more convenient than a disc.

I didn’t get the impression the guy encoding the resulting files (who I was responding to, not you) to H264, AC3 and didn’t seem to grok what a container was was keeping around these MKVs.

Yes, if you’re archiving blu rays MKV is king. If you’re ditching them after encoding why involve another application and step, that’s all I was telling him.
