[mythtv] MythGame screenshots

[Jochen Kühner]

If now tested the script a few times and made some enhanchments, but my 
major problem is that i can't get a programm run in background from within a 
php script (i tested it with zsnes.) php still waits until zsnes is closed.

i used the system function from php the & backgroun operator and > /dev null 
2>&1 but it doesn't work. any suggestions???
