The gms stuff goes on your mythbackend, not your tablet =) .

The IP is your mythbackend IP, the port is wahtever port you're running gmythstream on, user is mysql root user name, pass is also mysql root user password, and database is mythconverg.

I've been able to bring up all of that info on my device, channel info and a list of recordings. But, gmythstream doesn't seem to want to compile nicely on opensuse =( .
