The only reason I still use tpb is the comments will usually let you know if a torrent is of poor quality, passworded, etc. Consider adding peer ratings for video and audio quality.
As for poor quality etc. here's our stance: by default, the first search result should be a release of 1) reasonable quality 2) reasonably well seeded.
For power users, we're working on user settings to adjust your preferences for release groups, etc.
Of course, working from a .avi/.mkv/.mp4 file would be optimal because we'd be able to get a lot of codec info from there, but we won't go so far.
That's actually pretty, pretty sad. Last week I've downloaded the most seeded torrent of the movie "In Time" and it came passworded.
I got all surprised because it was THE MOST SEEDED.
Wow, I've only seen passworded rar files on, say, DDL. We gotta be careful about that, thanks for the heads up!
