    Just bought a JVC XV-N40 for my 16:9 tv. It says "Digital Direct Progressive Scan" on the front. There is a switch on the back that has 3 settings: Remote, 480p, and 480i. Which of these should I set it to? What do they mean?
    Thanks.

    Remote Control select, 480 lines Progressive, 480 lines Interlaced.

    Go for Remote or 480P

    Use remote then your remote control can switch between progressive and interlaced. Try each and see which you like better. You need a digital/HDTV to use progressive, if you have an old analog TV you can only use interlaced. If you need interlaced just select that with the switch on the back.

    Yes progressive scan requires a digital/HDTV, interlaced is the old standard used by analog TVs. Interlace sends 60 fields/sec (each field is half of a frame, but the two fields don't always match up) while progressive sends 60 full frames/sec. With interlaced you can get combing where movement causes fields to mis-match.

    Actually, I believe it's 30 full frames per second.

    Jake, 480p progressive will be the best choice for the Toshiba you own.

    Cliff, it is indeed 60 frames/sec. You're probably confused with interlace where 60 fields per second equals 30 frames per second (well, sort of...).

    Generally, it's 30 frames per second interlaced for video sources, 24 frames per second progressive for film sources.

    Yes film-based sources are originally 24frames/sec but 480p always outputs at 60frames/sec. For film source they duplicate frames in a 2 then 3 multiple to get an average 2.5x frame rate since 60=2.5*24.
