TVquality is generally considered to be30fps (24 for film),perhaps you are thinking of scan rate, which is 60 hz in the USA (and some other parts of the world) and 50 hz in most other countries.
With HD now, 60 fpswill eventually emerge as a standard.
Oh....true! You're right about that. Before, I just recalled that PAL had 50 frames/sec or something, but turns out it is 50 half-frames per sec, so it's 25 full frames/sec. So 30 fps is great already.
