Your cable should work to watch a movie - for more advanced features, for which you would need the latest preamp/processor, etc. you will want to upgrade to an HDMI 1.4 or higher cable (bandwidth I think). The good news is that you can get a really nice color HDMI cable from somewhere like monoprice.com for about 10 bucks. For longer lengths they cost more of course. I would order one, because it may well perform better even if you don't need the 1.4 spec. While you are at it, order several cables and adapters that you may ever possibly need, because the price is unbelievable compared to shopping in brick and mortar stores! They have quality stuff.
