Also, for the record, in the US, the prices to buy English TV productions on DVD are outrageous. I don't know what it's like in Canada.
For example, the complete collection of
Fawlty Towers sells for $46 at Amazon.
The Young Ones is $49. That's about $4 an episode. If you look at US TV shows from the same time period on DVD, you find that the first season of, say,
Taxi is available for $29, or about $1.32 an episode. And, for some reason, you can get the first season of
Night Court for $8.39. That's $0.65 an episode. (This is actually remarkably cheap.)
And you can forget about getting lesser-known British TV shows. Of the BBC's
Top Ten Sitcoms, only the top six are available at all. You can forget less popular shows. And you can forget about classic
Doctor Who. I don't know what the deal is, but not only can't you get it on DVD (except for some apparently randomly chosen episodes), but no one airs it any more, either, even BBC America, although the new series are shown both by them and by the SciFi Channel.
