For reference, this is my setup:Time Warner Cable in Austin, Texas with gamer speed, on really old shared wiring that is so bad there isn't enough power to get actual cable--I just have cable internet; a MediaLink router; a four-year-old Korean re-branded Viore monitor without a working antenna, but with three HDMI ports; and, a two-year old basic Dell, factory setup laptop.Having said that:  my cable service, despite paying for "gamer speed", is pretty shoddy during peak hours.  HuluPlus and Amazon on Demand seem to have packet streaming that deals with that pretty well--I have to restart movies during peak hours, two or three times, but other than that I don't have much interruption.But, I thought this didn't work at all with a two-year-old Dell laptop because it couldn't connect during peak hours. (It wouldn't work at 10 p.m. on a Monday night). Then, my boyfriend got it to "Cast" using a Samsung phone at about 11:00 p.m.. We like to watch very old Led Zeppelin videos on YouTube, and it did work well for that. The video and audio with even really old footage is excellent.The next day, I had no problem at all getting it to cast at 1:00 a.m., from my laptop.  As of this writing, though, I don't think it works unless your cable is really good.If you have bad internet, this isn't worth the money.  The free Netflix is nice, though. 

Question: How was tthe video quality?
Answer: The video and audio with even really old footage is excellent
