Re: understanding 60i vs 29.97fps (?)

well, i did some research that 60i is 29.97fps not 60fps

to dumb this all down, my real question is:

what kind of "look" will I have on the HDTV if my bluray disc is rendered:

1)with all progressive settings? will it look film-like with no interlaced lines? will I lose some of the sharpness?

2) what if its rendered with default interlaced settings? does this give it more sharpness and looks like "live" TV? any trade-offs?
