Cseries :: Can't Stream Videos From Most Of The Sites?

i'm wondering if this happens to anyone because i can't stream videos from most of the sites. here are a few to list:startv.inInternet.combcci.tvcrictime.cometc.....i use wifi to stream the videos but with little success.even in Internet video doesn't start and clicking on "switch to standard player" even doesn't work.(it infinitely circles in round and round)only mobile version of Internet works well.there are a few sites also where video works good untill i touch seek bar. and after that it goes blank.
