77 does not have an EPG on it's own satellite, it's part of the same ARC as 61.5 and 72 so their EPG covers it.
110/119/129 is set up the same for that ARC. 110 has a 44 HR guide that covers the ARC, 119 has both a 44 Hr guide and a 9 day guide that covers the ARC.
To complete the answer - 118 has a 44 Hr guide, and is covered under the WA with guides on 110/119
