As a member of the Primestar group when they went belly up it was pretty simple...they changed you to Direct. Where I was it was Pegasus (Pegasuck..they had alot of rural areas..they were like a reseller of Direct except they had higher prices. You couldnt get Direct directly from them in those areas) and they changed us to Direct about 2 weeks after they bought out P*...and we switched to Dish about a month later
Primestar never had a Circualr LNB....they had one linear and 2 linear at the end (they moved from 85 to 89W near the end and was going to beam up via both satellites for more channels)
