Although this doesn't have the selection of some sights, I enjoy the simplicity of using this to watch the content they have. I listed another site (I will at the bottom of the page) but Coke and Popcorn is an easy site to find seasons of streaming TV series. A great way to spend a weekend or two watching a series you never got a chance to watch but wanted too.http://www.cokeandpopcorn.com/
Then there is Tube Plus - a bit trickier and I highly recommend your virus software is up to date just in case. They ask for (sometimes a Code-V plug-in) I have heard bad things about this and don't play Movies or TV shows that ask to install it - but I notice that Internet Explorer has the plug-in already, so watching the shows is as simple as clicking on them.
The big difference, is Tube Plus has movies, DVD, Cams, all the stuff you hear about on the net - I only mention this sight for the adventurous and as with Coke and Popcorn, play at your own risk.http://www.tubeplus.me/
These sights are listed in STUMBLE - a highly customizable search engine that allows you to choose the topics you are interested in and sub-topics, etc.. I enjoy www.stumble.com
a lot, we find recipes and interesting science stuff that I doubt we'd find otherwise.
Give them a shot (all warnings aside) and get to see entire seasons of shows like Breaking Bad, Weeds, It's always Sunny in Philadelphia, etc..
I can say with a degree of certainty that I have never gotten a virus warning from these sites, unlike downloading torrents which is a whole different beast.
