There are two ioctls potentially involved, either CDROM_SELECT_SPEED is
reporting success or, if it failed, then SG_IO GPCMD_SET_STREAMING is
I suggest looking here: libmyth/mythcdrom-linux.cpp
(MythCDROMLinux::setSpeed approximately line 444) add some debugging
statements. Figure out what is failing (or rather, erroneously succeeding)
and what is required to fix it.
