The 4 tuner lease limit is broken all the time. I have 6 leased tuners and I didn't write to the CEO office. Just called and asked for it.
They didn't let me break the rule when I called and asked for a 722 to replace an old 4800. I've been a customer for 10 years and was talking to a 5-star CSR. I had to settle for a 612 instead
Annoying. . .
Heck I'll buy it. Can always use another OTA tuner
