Advice on Dish HD receiver(s)

first thing is that you are in the eastern arc and to receive almost every hd channel is just aim at sat 72.7 you won't receive any locals but everything else.i have the 622 receiver and get local channels wherever i am off batwing which is hooked to dish receiver then scan for locals through receiver,on menu after option 6 system set uo then option 9 for locals ,you must have sat signal before this will work locals will show up on program guide and all info,as far as hd on second tv i don't believ you will receiv it through home distreibution,you also don't receive local off air channels on second output of receiver i just leave mine on single mode and all is good can still dvr as normal.
