I don't think you can rule out hardware.  I'm assuming that you're using
different drives with your MythTV box and your Mac; what happens if you plug
your MythTV box's optical drive into your Mac and play a disc from there (or
the other way around: plug your Mac's optical drive into your MythTV box)?
It's possible that one drive is less tolerant of scratches and other defects
than the other.
