Usually they just change the specific way that digits are sent. I've 
seen this during upgrades of their SA4250 and 3250 as well.

My suggestion is try the other options for "mythchanger -f". For one of 
my SA/Cisco STB's I use "2" and for the other I use "4". But try the 
entire range until you find one.
