Based on info provided in this forum, I believe theproduct that most fits my needs is Roku Express, but I need further clarification.
The description for Roku Express says "Stream free TV, live news, sports, music, movies, and more." Does "Free TV" mean programs that I current get using my indoor antenna (Mohu)? If so, then how would I watch a sport program for a station that isn't receivable with the Mohu?
Streaming and things on your antenna are totally separate things.
There are thousands of channels on Roku. Some are paid (HBO, Netflix, Amazon etc.) and some are free (with commercials.) Some have various "hybrid" models like: pay a little and get a few commercials, pay more and get none, or "free" if you have a cable or satellite TV provider. It's a little complicated at first - kind of the wild wild west, but you'll figure it out.
Permit me to re-state my question. I've decided on Roku Express, mainly because it's the best fit for my budget My only remaining concern is whether Express will still utilize the Mohu antenna, even though I expect to attach Express with an HDMI cable. That concern derives from the fact that I get tons of pixelation with the Mohu. If Express will still utilize the Mohu, then I expect that I will still get the same degree of pixelation.
Assuming that the answer is "Yes, Express will rely on the Mohu," then I would ask whether another of the Roku products (obviously with a higher price tag) would work around the Mohu, thus eliminating the pixelation?
