I've had a 36" Toshiba Picture frame telly since last summer. I've been thinking I'd like to upgrade my dvd player to one with progressive scan, as the tv is a 100hz one. A fair amount of my dvd collection are NTSC. How do 100 hz telly's play NTSC movies? Do they ramp it up to 120hz, or drop down to 60hz? Would I only benefit from PAL dvd's with prog scan and this telly? If I've completely missunderstood the details of prog scan, please correct me.....! Thanks!
