I'm in the Philadelphia TV market and have been using Channels DVR with an HDHR Flex to get my locals. The local broadcast changes caused by the FCC repack made CBS spotty and unreliable in bad weather and eliminated ABC reception. We didn't didn't really care about the loss of ABC until the NFL scheduled a Monday night Eagles game for Sept 19 on ABC. So in early September I signed up with Fubo, added the lineup to Channels and clicked the Experimental checkbox to enable Local Networks via TV Everywhere.
Local TVE under Fubo has worked perfectly for us since day 1. We record/watch the news on Fubo ABC daily; watch Fubo CBS more and more as the OTA reception gets worse and worse; and watch Fubo Comet because the quality of the signal is so much better than the bit-starved OTA sub-channel. I ended up keeping Fubo because in addition to the locals I got hooked on the sports availability. Aside from MNF, I got to watch all the MLB-NL playoffs -- Phillies went to the World Series.
So I can say that in the Philadelphia market, TVE Fubo and Local Network TVE Fubo has worked perfectly under Channels DVR. I've never had to reauthorize since I originally set it up.
