Hi, I am new to the Chromecast having just received it the other day. I bought it mainly for the ability to cast video from the Chrome browser. I realize it's not optimized for this purpose at the moment, but I've read a lot of user reviews in which people have had much more success than I have had so far.
First, I have tried streaming from ESPN3 and a couple of streaming tv stations (German language ARD and ZDF). I had no trouble with any of these sites when I had my laptop connected directly via HDMI. My router is 10 feet away from my laptop, and I have Performance Internet from Comcast (up to 30 mbps). My laptop is a Lenovo G85, i3, 4gb memory, Windows8. Certainly not a high performance pc, but it meets the minumum requirements for streaming in SD at least. I can cast the website itself with no trouble, but as soon as I try to play a video and cast that, I get nothing in the player on my tv--video or audio. Not even a choppy playback as others have noted. Also, if I click fullscreen on my laptop, nothing changes on the tv. I have noticed on the German sites (or at least one of them, can't remember) video will play within the original window, but not when I try to go fullscreen. I don't know if it's a flash or silverlight or some other setting that is blocking the Chromecast. I have set the device to the lowest (480p) setting and it doesn't have any effect. It works fine for Netflix and YouTube. Since so many people have reported success with the Chrome browser casting from sites like ESPN3, I am hoping it is just a matter of troubleshooting and not just SOL because of my laptop. I have a hard time believing everybody who has successfully casted video from their Chrome browser is using super-fast gaming pcs. Thanks for any tips/comments.
