Checking WTRF's OTA signal this afternoon, I noted they seem to be doing pretty well putting out three HD channels simultaneously. There are, however, occasional video glitches (and quicker, less noticeable audio ones) that probably indicate they are living on the edge so far as compression is concerned. All three sub-channels are probably just a little "softer" than I like on a larger screen but probably not as noticeable on smaller displays. I'm wondering how all of this holds up when two or more channels carry high action programming? What I watched today was all minimal action shows like "Judge Judy" etc.
