1. "Why can't I watch videos off of websites like CBS or VH1??"
2. It's not a PC.
Some seem to dance around this but let me give it to you straight. The industry is at odds over this along with patent issues. What this means is that while it is technically possible the industry and patent system means it may not work as well as your average PC web browser.
In fact it's well discussed how Hulu wants Hulu Plus on devices and not the usual hulu.com. The hulu.com site and streamer sniffs out it's not a PC and fails to play.
Do not count on a PC like experience.
I am interested in purchasing a Samsung 55D6300 but have some questions on the web browser app. I understand that the web browser supports flash and can stream SOME media. My main question is what are the limits of streaming data from websites, ie, videos from FOX, CBS, NBC, TBS, etc? I would love to cancel my cable and use the TV to stream the free content online. I have been unable to find the answer to this exact question in my days of research.
