SD is always 240 lines. It's called 480 Interlaced!
-------------------------------------
480 interlaced is not 240 lines it's 480 lines. Yes, it's made from two (slightly different) 240 line fields but the result is 480 lines of resolution when they're combined. That's like saying 1080 interlaced is has only 540 lines of resolution.
With the SD I'm seeing, if I freeze the pic when there is a nice hard diagonal line, I can count the "stair steps". There are only 240 of them from top to bottom. I'm pretty sure my old NTSC analog TV produced better diagonals. Though I couldn't freeze the picture to count them. If there are really 480 lines of data why are the stair steps so huge? I think I'll put in a DVD that has 480 lines and see if the same number of stair steps occur on diagonals. What ever the reason, the SD picture sucks IMO.
