HR20: Radically different signal readings between tuner 1 and tuner 2?

[cheebs]

I only ran my second line for tuner 2 this weekend. Imagine my surprise when running the signal meter, the readings were wildly different (much, much lower on tuner 2). At first, I thought I had messed something up in the install.

Flipped the lines (tuner 2's line to tuner 1) and the readings were the same!

Not satisfied, I dug up another HR20 to see if it was this particular unit's problem and the readings once again varied wildly, with tuner 2 showing significantly less signal. Even flipped the lines once again, same situation!

Anyone had this happen?

Ok, thanks for that.

My symptoms are pretty much identical to the OP on that thread... I'll try the resetting multiswitch thing, mine is a 5x12, don't have a Ka/Ku dish yet. Strange that I had the exact same problem on 2 different DVRs.
