PTP for TV BTN for games
BG or
BCG (only open registration/irc invites) and for e-learning bitme or bitspyder. For apps you can select any 0day/general tracker like
SCC (best 0day selection also all free) or
IPT. Now HD trackers there are many of them that have great internal uploading groups. CHD, HDC, TTG, HD-Torrents are just a few great HD trackers out there. You need to select for yourself what is best for you. It's always depends on what content you are looking for. You can say HD but there are FullHD 720p 1080p formats or old/new movies you really need to know specificly what kind of content you want to download and than you can look for the tracker that have the best selections of this torrents
