Description
Using MacOS 10.7 (or 10.6)
MythFrontend will fail to play any DVD
When selecting the play DVD option in the Optical Menu ; in the log you get:
libdvdread: Using libdvdcss version 1.2.9 for DVD access libdvdread: Can't stat /dev/r/dev/disk1 No such file or directory libdvdread: Could not open /dev/r/dev/disk1 libdvdnav: vm: failed to open/read the DVD 2012-02-22 21:33:51.365260 I MediaMonitor::selectDrivePopup(Select a DVD drive) - No suitable devices 2012-02-22 21:33:51.366886 I DVDInfo: Trying dvd://dev/r/dev/disk1 2012-02-22 21:33:51.369193 E DVDInfo: Failed to open device at /dev/r/dev/disk1 2012-02-22 21:33:51.369200 I DVDInfo: Finishing.
programs/mythfrontend/main.cpp automatically prefix the device name with /dev/r
Yet, the default device name it isn't defined by the user is /dev/disk1 (defined in libs/libmyth/mediamonitor_darwin.h
The documentation in the settings statea: "This device must exist, and the user playing the DVD needs to have read permission on the device. 'default' will let the MediaMonitor? choose a device"
using "default" does nothing, it uses /dev/disk1 unless defined in the settings, and default is /dev/disk1 which myth try to play as /dev/r/dev/disk1 which will *always* be an invalid device
The log also shows: MediaMonitor::selectDrivePopup(Select a DVD drive) - No suitable devices
No such popup ever appears...
MythFrontend should either automatically determine what the right DVD device is, not prepend /dev/r to any path name or properly display the selectDrivePopup

Better default device (when MediaMonitor? disabled) on OS X. Refs #10370
OS X uses both the BSD and raw device paths, so the MediaMonitor? supplies names like disk1 instead of /dev/disk1.

If there is no DVD mounted, selectDrivePopup() tries to return a default like /dev/dvd on Linux, or D: on Windows. On OS X, it should default to disk1, not /dev/disk1. I will commit a change in mediamonitor-darwin.h. There are other problems for playing DVDs, though - will try to spend some time investigating.
All this code was my poorely-designed kludge to support multiple drives. selectDrivePopup() could return NULL if there is no suitable device containing suitable media, but that sort of assumes the user has to have the MediaMonitor? enabled. The hard-coded default was for users who don't want the extra process/DBus/uDev/DiskArbitration overhead, and turned off the MediaMonitor?
