In no specific order
Porridge
One Foot In The Grave
Spaced
I'm Alan Partridge
Red Dwarf, series 4 to 6
Dad's Army
Only Fools I'd include but only the latter half-hour ones and the earlier 50-minute ones (plus the Jolly Boys Outing special which is a classic).
violet, you mentioned some real old chestnuts there. Yes I remember Both Ends Meet - what an odd one to suddenly pluck out of the ether! I also remember Chance In A MIllion being on but only saw a snippet of it. My brother said it was very funny and that one thing that appealed to him was the Callow character's stilted way of speaking - "Brick. Through window. Note attached." Another short-lived, one-series one was An Actor's Life For Me, which bordered on the surreal at times and featured a great turn from Victor Spinetti. It also had an amazingly downbeat ending and then that was it - gone, never to return.
littleoldme, you are NOT alone - Victoria Wood did some good stuff but yes she is massively overrated and seems to be treated (along with Julie Walters) as some sort of national treasure. If I'm watching something with her on and she sits at the piano to do one of her songs, my heart sinks and I switch over. Dinnerladies was okay, a bit dull, I've seen worse but it's not that great.
