IIRC, TSN HD and TSN2 HD require Sports 1. Raptors HD and Sportsnet HD require Sports 2. I don't think the others have any SD dependencies. You need 4 HD theme packs to get the $10 4 theme HD bundle that includes time shifted HD Nets though. That means you either must either pay $16 for 3 themes and HD Nets or pay for Sports 1 or 2 to get them for $10. OTOH, some CSRs can provide 4 HD theme packs without Sports 1/2. Got that?!
