I just noticed those idiots at PlutoTV have removed there British Comedy Channel. A better alternative is XPTV'S: XPTVUK
It can be viewed on the Stream on the budget showcase app on ROKU and go to XPTV.
Among the line up: Fawlty Towers, Benny Hill, Only fools and horses, Father Ted, Are you being served? , Monty Python just to name a few.

It seemed like they were showing Monty Python an awful lot the last couple of months.
