Yes, prime-time starts at 8. Who has time to get home, make dinner, eat and clean up by 7:00? No one, which is why 7:00 and 7:30 are filled with sitcom re-runs and Entertainment Tonight.
I don't usually get home from work until 9-9:30, so I miss everything. I haven't seen an episode of Lost in about a month - I'm going into withdrawal.
Just remember, everything is half an hour later in Newfoundland.
Get a PVR man, I never watch anything live and I get home at 5:15, if I were in your situation a PVR would be a must!
