If you are going to watch Toudou, LeTV, AiQiYi etc then they'll usually ask for a fee for any movie worth watching, even if it is 20-30元 a month. More than the price its the payment methods which you may find annoying.
I suggest you go to 乐享网 and get a free VIP username and password for the site you need, save yourself a few pennies.
there's a shop on Baita lu (the part of Baita Lu that is halfway between the Renmin Dong Lu and DongFeng Dong Lu) which sells DVDs for about 10 yuan each, I don't know Kunming very well so not sure where you live and how far away that is. It would be about a 15 minute wall from DongFengSquare metro station. I'm not sure how reliable finding the right DVD in the right language would be there.
Camera stuff is best bought at Yuantong North Road better known as computer street, a side street of 121 road.
