Not a dumb question at all :) I don’t actually think all of the season one episodes are on tpb in 720p. You can download the full season in 720p rather than one episode at a time if you wanted to do that. TPB isn’t working for me right now though, otherwise I would try to find a link for you. I got my 720p download for season 1 on this site though, the list of 720p glee torrents is here.

Also when it comes to searching, if I was wanting to search for episode twelve of season 1, I would just search ‘glee s01e12’. Just change the numbers to suit the episode you’re looking for, and find the 720p there :)
