I'm shocked, even I support the beloved BBC! I probably watch as much as you, mostly films, and mostly downloaded. My wife is the TV expert these days, for some sad reason I am totally impressed she can stop a program midway and then go back to it.
Always reminds me of the old joke when the man demonstrates this to the old lady, and she says won't that upset everyone else who is watching it? I recently got hold of a copy of "In which we serve" an old war film made in 1942 - a true classic. Now I just need the right moment to watch it.
