Well there shouldn't be any SWM upgrades, but techs can bend the rules sometimes.
But you'll have to get rid if the legacy box.
Can you clarify the "no SWM upgrade"? How else would 9 tuners be supported? Sorry, I'm still trying to figure out this SWM stuff.
Also, will they swap the legacy box (leased) for an HD box if the TV is not HD? I would be happy to connect it through S-Video or component and be able to watch down-rezed HD channels!
