You can't use normal splitters like you do with cable tv. Satellite receivers send a voltage signal to the LNB and putting a normal cable tv splitter between the LNB and the switch and/or receiver will confuse it.
I would strongly recommend that you take the 2700 receiver and try it on one of the lines going into the 9200 as suggested by i hate tv. Run a check switch when connected to this line.
If this works, then your problem is somewhere between the SW44 and the 2700 receiver. #1 suspect would be cabling, #2 suspect would be the SW44 itself. Also, make sure that you are using all legacy equipment (LNB's & SW44) as the 2700 receiver is not compatible with DP or DPP equipment.
I have a complicated set-up myself, running high frequency splitters (for satellite use), two SW44's, and a 9200, 5200, 4700 and a 2700 receiver. Everything works great. I did have one bad output on a SW44 myself, but the other three outputs worked fine.
Hope this helps.
