Also saw on tivocommunity.com that RS is Reed Solomon. Digital transmission systems incorporate a scheme called Forward Error Correction which uses Reed Solomon error correction codes
That is correct. However, the FEC has a limit to how many errors it is able to correct. Any further errors are uncorrected.

RS Corrected indicates that the demodulator detected a block with an error in it and the RS code was able to correct the error. RS Uncorrected means the error was beyond the capability of the RS code to correct. An uncorrected block most likely will result in a pixelation or a dropout event.
Good explanation.

What is odd though, I haven't seen any corrected errors in your test results. If there were any errors to be corrected, they should first show in corrected errors, which is why I asked you before if you had corrected and uncorrected reversed.

So, I'm wondering is it that the Roamio tuner is not able to correct any errors, and all errors become uncorrected. Or is it that it is able to correct some errors, but it is not showing how many?

I'm sure I will have more questions but are you saying I need that power strip you linked instead of the one I am using?
The one that you have is just fine, no problem.
