Hi everyone,
As most HR20 users, I too have battled a long series of issues with this box, but I wanted to share a thesis (need more data points to be conclusive) that part of the issues many of us have had relates to getting the cleanest signals to and from the dish.
My install of the new AT9 (replacing a 3LNB dish, as I've been on HD for many years) went smoothly enough, but after two weeks, the main LNB (103 sats had no signal) went out. Installed came back and replaced LNB's, and presto, good signal.
However, signal strength was not the best (and had not been on 103), and the HR20's (and the other Tivo DVR's) were pretty warm driving the dish though a Zimwell 6x8 multiswitch.
The zimwell is about 60' of cable downstream from the dish, three DVRs (including 1 HR20) are 10' from the switch.
The installer (and posts here) indicated that the HR20 required the exclusive use of the Zimwell 6x8 multiswitch, and that my existing Spaun could not be leveraged.
Therefore, for about a month, I ran five DVRs thorugh the 6x8. During which time, I experienced many of the Sat signal issues mentioned in other threads. I know some of this could be software version related, but for me, it was fairly consistent across versions.
After removing the B-block coverters (which are not required at this point in time) and seeing some diminution of the issues, I began to wonder if the problem is that the receivers can not adequately power the configuration.
Even with multiple receivers, I think a lot people (myself included before this) are pushing the limits of the voltage consistency a value-engineered CE device can supply. Many of the recording issues could be linked to momentary weak voltages not switching LNB's or glitching the LNB and/or multiswitch.
So I decided to power the dish by cascading in my nice SPAUN 5802 NF powered multiswitch (a ~$500 piece) to drive the dish through the new D* supplied Zimwell 6x8 multiswitch.
The SPAUN provides the power to the dish, so it de-stresses the receivers. Normally, the receivers need to supply the voltages to drive and select the LNB's through the multiswitch. I can confirm that this is helping, as the receivers now run a heck of lot cooler and touching the output cables on the receivers is barely above room temp, whereas before they were hot.
Since I've deployed the Spaun, all the DVR's have been doing great. Attached is the diagram of my current setup.
Currently, instead of the above, I'd recommend people get the new wideband Spaun (plus associated power adapter)

For people just looking to add power to the dish and finding the Zimwell 6x8 is enough outputs, you can add power with this device:

For only $50, a cheap way to solve a lot of headaches related to dish and LNB issues
What have some of you experienced with respect to adding powered switches or drivers?
