Radio Shack won't have the Zinwell WB68 multiswitch you need; if they have a switch, it will likely be an obsolete model.
But in most cases, if you only have 2 HD-DVRs, you don't have a separate switch anyway (there's a 4-output switch built into the LNB pack). If the LNB is bad, or if the dish is out of alignment, a switch won't help at all.
Depending on how willing you are to do work on your dish, we might be able to help you.
