Profile parsing error: output format invalid
Failed to load conversion profile from file '/Users/tim/.MakeMKV/profile1.mmcp.xml'
Optical drive "DVD+R-DL MATSHITA DVD-R UJ-8A8 HB14" opened in DASPI v1.3 mode.
This is expected behavior as updated in sticky post at http://www.makemkv.com/forum2/viewtopic.php?f=10&t=4386 . Profile syntax changed in 1.7.3 ; if all you care is track selection, then just use default profile that comes with program and set your default selection string in preferences, on advanced tab.
