The majority of video on the web is made to play in Adobe Flashplayer, for example on You Tube. The Flash player is a plugin that is required to view Flash based movies within your web browser.
Flash is being faded out on the web and is slowly being taken over by a html 5 player. Unfortunatly for some Appple and Adobe don't get on like they used to. Apple no longer supports Flash on it mobile devices or ipad's.
I have just come across this that may be of help
http://itunes.apple.com/gb/app/iswifter ... 57173?mt=8 I don't know what it's like as I have not tried it, but it may be a solution in the meantime untill You Tube and all these other sites make the swap to html5.
Hope that helps, but IMHO I would just use a Computer not the Ipad and then you will be able to view the web in all it's glory
Have Fun
