I need some confidence on my rips.

Hi, I backup my Bluray ISOs into MKV files using MakeMKV.

The thing is, it is said to be still in beta status, and I'm getting a little paranoia here.

It played okay but how can I be sure of my rips integrity?

Should I need to make MKVs again whenever there's an update?

that's right you are paranoid

Should I need to make MKVs again whenever there's an update?

Of course not. Straight from MakeMKV description:
"but not changing it in any way(no video and audio reconversion)."
