I don't want to put it up here as I don't want the address too public :-) but i'm happy to pm it to anyone who needs it.

Alternatively, I got it from here http://proxy-list.org/en/index.php - generate a list and try a few until it works....

- and I wouldn't trust an open proxy for any of my other stuff, but who cares if someone is listening in to the tivo slices! :-)
