Why not avoid sudo altogether and just grant world read/write
permissions to the port? It would simplify things, and shouldn't really
be a security concern on a home Linux box, especially a dedicated Myth
box that only has a DirecTV receiver attached.
So just "chmod a+rw /dev/ttyS0" drop the sudo and see if it works then.
If you're really paranoid about security you could set the group on
/dev/ttyS0 to mythtv or whatever your myth login group is and likewise
set the same group on the directv.pl script. Then you can just allow
group read/write on the device.
