300 Blu compared to 300 HD Satalite?

[Chris60119]

I do not own this movie yet. I saw it when it first came out on disc on a small 27" tv non HD. I've been wanting to buy it, and I see it's in the bargin box at Amazon. Now I read the reviews and it says the grain is supposed to be there. On the Satalite dish last night there seemed to be a LOT of it. I'm guessing Blu Rays have better quality then what coming through my satalite dish. I have direcTV. Other then the two coax cables from the satalite to the satalite box. Everything is hooked up with HDMI cables. My question is. Does the 300 Blu have less grain then what I saw on Tv last night? Also, the new 300 limited edition comong out. Is that the same movie disc that is in the one thats already out now? I'm not an extra guy so I'll go for the deal if it's the same quality.
