Where can I watch this?

If you live in the Dallas/Ft. Worth area, they are currently airing it on the local PBS Station KERA Channel 13. If not, try the local PBS station where you live. Don't bother with BBC America because they're more interested in showing Gordon Ramsey cuss restaurant owners out than airing classic British comedies. What a disappointment that network turned out to be.

I usually watch it on my PBS station every few years or so they'll run the series

In case you waited 8 years for this , LOL.
