I see classic 1 and 2, classic match 1 and 2, match 1 and 2, and pub 1 and 2. Isn't that all of them?
I think the reason they weren't showing up in other server browsers was because id's master server went down (that's my guess as to why they referenced id software). I don't know why they wouldn't show up in the paintball2 browser, though. Sometimes packets just get lost and you have to refresh a couple times.
