i'm wondering what i can do with these, can i plug in an external hard drive and play a movie i have saved off of it
It should work. I just got the PN50B850 a while ago and it works on it with "Samsung Media 2.0". It should work with most of the Series 6-8 on LCD, LED, & Plasma. Do you have a link to the TV? I don't think there is a B630 for the 40 inch, there is though for the 52 inch. Do you mean the A630? If yes, I think that model doesn't have USB 2.0 Movie, just for music and photos. What's your price range, and what size of the TV do you want? I can suggest a different Samsung model for you.
here is the link through bestbuy http://www.bestbuy.com/site/Samsung...HDTV/9300437.p?id=1218079755374&skuId=9300437
Oh ok sorry, I was looking at the Canadian Samsung Website, that's why I couldn't find it. Yes, USB 2.0 Movie should work with it then. Here's a link of the supported formats it can play: http://www.samsung.com/ca/consumer/learningresources/medi2.0/usb_faq.html
