Mike, you suggested "As a workaround you might have luck by doing an ENCRYPTED disc backup with MakeMKV first, and then opening this backup from a hard drive." I tried that and got basically the same errors and MakeMVK shut down.

I'm running Vista Ultimate SP2 on an Intel Core 2 Duo CPU E7400 @2.8 GHz with 4GB ram I've never had any issues with MakeMKV until I installed the latest version

I'm having the same proplem. I get an error message that the MakeMKV application console has stopped working, then a popup[that says fatal error has occurred and mae mkv will now close. I haven't been able to find the previous version of MakeMKV so I can re-install it
