It's hard to find a fast, genuine downloadable link unless u're willing to pay for it. I know, we all can find free download links everywhere in the internet but the downloading is damn slow.. It could take years just to download a decent tv series.
Watching it online is another option if u can find free and fast video streaming link but that's also hard to get. I'm using umobile for my connection, so the buffering thingy really makes me crazy.. I found 1-2 nice places for streaming vids but of course, they have some weak points. And I'm not going to tell you where is it coz I wanna save the bandwith just 4 me :P..
You can use these links to download heroes or in fact any other tv series or any latest movies or music clips or games..
