ILLEGAL REQUEST:READ OF SCRAMBLED SECTOR

[lllusion]

Whenever I get this ILLEGAL REQUEST message, I close MakeMKV, then run VLC....
Hope this helps people who have been getting this error.

This solved the issue for me. The only difference is that MakeMKV can remain open while launching VLC and opening the DVD. VLC can remain open if desired. Open Disc has to reinitiated in MakeMKV in order to access the disk and scan contents.
