Ok by downsampling I mean that since my TV is only 1366 x 768 (yet can still take 1080i), the PS3 does this downsampling to make the 1080p picture fit into the 1366 x 768 limitations and thus makes the grain more visible. Thats what I think. There are rumors (hope its true) that Sony is going to fix the downsampling problem for 1080i tv's on a future PS3 update along with adding 1080p upscaling for regular dvd's. Keep your fingers crossed
Thanks for all your help again,
