use for a DVR because I only watch sports live, so I just use my Roku. I had very few problems streaming the NCAA tourney. That said, I lost almost all interest after BYU lost in the First Four. I have had occasional quality problems when streaming games, but never to the point of being unwatchable. The small loss in quality I get for streaming is more than made up for by the $$$ I save by not having a cable subscription/contract.
