iPad with Retina

Hello,

I recently received an iPad with Retina Display and, so far I like it. I use it for school, mostly, but there are huge gaps in between some of my classes, therefore, I sometimes have nothing to do in between these 3 to 4 hours breaks. I was wondering if it was possible to download and watch anime and/or TV shows on the iPad? My iPad is not jailbroken, I don't think it can be jailbroken with the IOS that I have now, so I don't think I could use torrents, unless someone could interject and show me how to do it. Is it possible to download the anime or TV shows directly onto the iPad or would I have to download them on my computer and transfer it to the iPad? Also, I usually download the 720p of any anime release, will the iPad support the 720p that are MKV? Or would I have to convert them to AVI or MP4?

Thank you,
