If you need a third orbital location (61.5, 129, or 148 only, not 105 or 121) for the requested programming, you could have 2 dishes, with the line from the 3rd sat signal feeding into the 3rd port of a DPP Twin, but with this config, you can only run two single tuners, or two dual tuners. And neither of these receiver configs would give you HD in four rooms... so, with that said.... WHY DID I WRITE THIS?!?!
Getting back to the issue,
asmcbride you need to decide what receivers you want. With only 2 lines going into your house, you need to pray that you don't need a 3rd line in. Assuming you DON'T need the 3rd line, here are your current options:
1)
The HD option: 4 rooms, all HD, using 4 ea. 811 receivers just as
webbydude mentioned. However, with this config, you get ZERO DVR capabilities.
2)
The SACRIFICE option: Don't know if you are able to lease 2 942's, but let's say you could (and you have the $500 to cough up to make this happen). You could then have HD in only 2 rooms, but DVR in all 4.
3)
The ABSOLUTELY FREAKIN' INSANE "COLLEGE FOR MY KIDS WAS OVERRATED ANYHOW" option: You lease and/or buy outright 4 ea. 942 receivers, change out the DP-34 switch mentioned earlier by
webbydude for a DPP-44 switch, and problem solved! HD AND DVR in all 4 rooms. Now all you have to do is memorize the amount of milk and butter you add to a box of KRAFT Mac-n-Cheeze, cuz that's all you be eatin' after this install
Of course, these facts will probably make you laugh (or cry) more than they will help. But really, if there are better options for HD in 4 rooms, and at least SOME of the TV's having DVR, I don't know about them.
I'm kicking myself for not paying attention to this training class: Does anyone know about the
811 receiver running in
QAM mode, and if so, could this apply to
asmcbride's situation?
