[QUOTE="kszabo, post: 253875, member: 61646"] They don´t have the same framerate. the 1080i and 1080p has exactly the same amount of pixel to cope with (decode), because 1080i is broadcasted with 50 fps (50 half pictures) and 1080p 25 fps (in PAL countries, maybe 24 fps for movies). 1080i half vertical resolution but double framerate. And good deinterlacing (like adaptive) does not half the framerate, so at last with 1080i you have double of created pixels per second (eg. you can watch football better with 1080i, more fluidity with better temporal resoulition). This is true for SD MPG2. I am not shure that Avivo can do vector adaptive deinterlacing for h264 1080i, I guess the maximum it can handle is "blend" and "bob". Maybe the ultra high-end GPUs can do better. Decent deinterlacing hardware for 1080 costs horror amount of money (50-100.000 USD) and are used only from professional studios.
