v1.6.3 fails to open disc

[CybrFyre]

The disc is the US version of Superman/Batman Apococylpese (ok, can't spell).

v.1.6.2 and v.1.6.3 on 64-bit Fedora 13.

fails to open this disc is one of three ways every time I retry...

1. on decrypting the MKB_RO, just hangs at 100% cpu... v1.6.2 I had to kill -9 the makemkvcon and makemkv gui processes from a terminal.

2. Repeatedly prints out the error: Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - AUTHENTICATION FAILURE' occurred while issuing SCSI command A30..00200740100720..05CEF180FE1F398345CF81BF7FD7A3F2C81 to device 'SG:dev_11:0'

3. after spinning for a moment at various spots, just prints ou "Failed to open disc"

thanks.

New failure mode upon retrying...

disc IDs as AACS v17

no disk read errors anywhere in dmesg, so don't think the disc is bad.
