msmith, do you see any PQ differences? When I got an HR22 to replace a H20-60 (best dog gone OTA tuner ever put into anything with a D* logo on it) I noticed softer PQ than what my HR20-700 has. I initially put the HR22 on the living room TV (at the time a 60" Sony) where my HR20 currently is and moved the HR20 upstairs (42" Magnavox). But to me the PQ wasn't as good on the HR22 as the HR20. So I put the HR20 back downstairs and moved the HR22 upstairs. I was disappointed because I wanted the doubled recording space that the HR22 provides on my downstairs TV. Now with MRV that need is less so but back then I mattered because at times I was having space issues on my HR20.
