With these pieces of software your torrents/TV shows and Youtube subscriptions automatically download to one easy to use interface(XBMC).
You can also use this interface to access streaming video services such as iPlayer and Radio services such as Radio 1 Extra. Using the XBMC Remote app on your smart phone you can control your video streaming with the usual buttons (pause/play/skip etc.).
There are no Ads on your Youtube subscriptions and Ads can be skipped if they are embedded in the videos by the content uploader.
I’d recommend using a laptop instead of a Pi, the Pi just doesn’t have enough grunt for this type of setup. Basically next time you have an old laptop lying around and you are thinking of a use for it, spend a few hours whacking linux and these tools on it and you wont look back.
