As per summary, all versions of makemkv greater than or equal to 1.10.9 require CONFIG_CHR_DEV_SG=y in the kernel in order to access optical drives. Version 1.10.8 still works without it, but it is considerably slower. If the kernel is compiled without CHR_DEV_SG, makemkv fails with "cannot find any valid optical drives"; if the option is present, all works fine. Upstream confirmed this (see thread at http://www.makemkv.com/forum2/viewtopic.php?f=3&t=16939 ). Is it possible to add a CONFIG_CHECK to future ebuilds?
