You're right. BBCAmerica used to run the series, but now they have some really banal "comedies" (I use the term loosely) in its place.

The one where he lost Wee Jock was a very good episode, and the books are even more charming. When the townspeople in the kilts came running out on the moor to keep him from shooting the guy, it was really a nice scene.

Hope the BBC brings them back.
