Sorry if you already answered this but what router are you using and is your TV running off of wifi or Ethernet? Maybe the amount of data/buffering YTTV is demanding when streaming live games, might be too much for your router to process quickly? Maybe the ESPN app demands less data/processing power for the router?I don’t think so. It’s a TCL with built in Roku. Looked like crap on YoutubeTV but was perfect on the ESPN app.
