[mythtvnz] Multiseat Myth?

[Brett Miller]

After closer observation (still limited) for decoding two streams with 
two Myth FEs ..

Think that one stream is being decoded by vpdau & the other by main CPU 
(65% load).
So does not work..
Might try two completely different applications in case there is an 
inter-dependancy between two Myth FE.
