A lot of torrent movie downloaders check for the "type of" print available - CamRip, Blue Ray RIP, DV RIP etc. It would be great if you could display these after the search goes through. It would make the movie download decision 1-click.
Displaying by default would confuse lambda users. How would you solve it UX-wise?
Another example[2], variously tagged HD720 and HD1080, with the latter clearly wrong.
We plan to develop our own crawler (instead of relying on other search engines), and refine our heuristics for tags / flagging false torrents.
In addition, you should also think about adding tags for CAM RIP, BR RIP, DVD RIP etc. Movie torrent downloaders do care about such information.
Disclaimer - I am a UI/UX autodidact.
We'll try to get as much as we can right by default until we ask for help from users :)
