Free2View has been around for a while now. I bought my Roku just so I could get it so I can watch Svengoolie.
I have to juggle my internet to work it, but, it works!
Our reception via antenna all depends on the weather. Some days we scan and find 90 stations lock in..only to disappear a few moments later. Nothing is more annoying than to attempt to watch a broadcast that pixelates constantly.
Best reception seems to appear after a storm. Clean air? Clouds? Why then is certainly a mystery.
