#6038: dvd speed control doesn't work correctly

DVD speed control when using the "Internal" player for DVD playback does
not work, resulting in the DVD spinning at maximum speed and making lots
of noise.
When using the "speedcontrol.c" program
(http://noto.de/speed/speedcontrol.c) and an external player e.g. xine or
vlc the DVD speed is correctly changed, resulting in a nice quiet DVD
watching experience.
The reason for the problem with the "Internal" player is that MythTV will
call CDROM_SELECT_SPEED ioctl, and only if this fails will it call SG_IO
to send the "SET_STREAMING" command to the DVD player, whereas the
speedcontrol program first sends the "SET_STREAMING" command and then (on
success) calls the CDROM_SELECT_SPEED ioctl. The solution is to modify
MythTV to call SG_IO first, and then (on success) the CDROM_SELECT_SPEED
ioctl.
