Pretty much everything I'd suggest has already been said by others so I'll just mumble over them.
Audio and visual - Obviously you've said she already watched television a lot, perhaps try some musicals, or musicals on CD as they're generally very enjoyable and a good way to keep occupied. Audio books are also great, -you don't have to worry about getting distracted from the words or eyes becomming tired, and you can just pootle around doing other things while you listen. As someone said, the Harry Potter tapes read by Steven Fry are extremely good, and I think now you can get them at a reasonable price or just borrow them from your local library.
Creative - There are so many things you could give her to work with (and again, many have been said!). Perhaps you could have a box full of bits and bobs- beads, felt, card, paper etc etc etc. She could make anything really -maybe you could ask her to make some Christmas cards or similar. She could try modelling with playdough or salt dough (which is easy to make) or you could buy her some paint-by-numbers or silk-painting sets which basically come layed out but you fill in the sections. It's easy, fun, and she'd have a good end result to be proud of, but unless you find a cheap supplier or they're selling them off in a sale they can be pretty expensive. If she's able to, you could get her to do some sewing, maybe make a little project out of it to make a bag or a cushion, and she could add on beads or shaped cloth. If there's a Hobbycraft [edit-suggested by the time I got to posting!] near you, make a visit- they're very good, and often have bargains- you'll probably get a lot of ideas by just looking around at what is on offer. Poster paints are availble in a wide range of colours and the Works sell big bottles for 99p each, which is comparitively very good value.
On the musical side, if you have a keyboard she could probably have a lot of fun with that -especially playing with the different sound effects etc. If you don't have one, keep your eye out at local car boot sales, faits, in charity shops and the like, as they often have some great bargains.
For an activity that would involve you a little, you could make some bread dough and then she could shape it in to plaited rolls which would probably be an enjoyable activity.
Blah, I've mumbled on with very little originality, perhaps you should make a bullet-point list of ideas and see which ones you think are solid possibilities.
