This. For example, we don't have a Seattle affiliate. I trick my DVR into thinking the Internet feed is a normal cable channel.
This right here is The Way. I run Channels DVR server on an old PC. One of the sources for the DVR is a free Sling login, which includes Buzzr and a handful of other free streaming channels. Works like a champ, although the timing is off sometimes.
The Harrisburg, PA market does not have OTA Buzzr. There is a lot of OTA activity in our market of late, with WGAL gaining a few new subchannels and some low-power signals spread throughout, but no one carries Buzzr.
I live within the very outer bands of theoretical reception for WTXF out of Philadelphia, but have never been able to receive them OTA.
