Here is the error log.
Faulting application Media Center 17.exe, version 17.0.189.0, time stamp 0x50917a6b, faulting module Media Center 17.exe, version 17.0.189.0, time stamp 0x50917a6b, exception code 0xc0000005, fault offset 0x006dc493, process id 0x2500, application start time 0x01ce495f8f522f47.
And there were a bunch of Bonjour errors in there too so I stopped it.
ERROR: handle_resolve_request bad interfaceIndex 24
Can it have something to do with having JR on 2 computers both able to control the PerfectwaveDac and the other computer with DNLA?
