Emerson LC190EM1 flatscreen w/ A1200

[watertonian]

Hello all. Think I might have posted something similar to this before, but I was wondering if anybody knew more about this tv? Its an Emerson, NTSC only flatscreen with HDMI, VGA, and composite inputs. I wanted to know more about flatscreen analog input tuners, and if they're hardware or software based. Or at least sufficiently software based that either a firmware modification or out-of-region update would allow it to tune in a PAL input? Not concerned about the actual tuner, just the composite/s-video input. I might be able to save a couple hundred US$ by doing things that way instead of getting one of these.
Also, I've gotten Picasso96 to utilize wide-screen resolutions (My WB is @ 1280x768x16bit now), but I can only get 320x200 or 320x256 resolutions by basically "letterboxing" a 640x480 (monitors lowest supported resolution). For some reason, it doesn't like doublescan signals, and the computer itself crashes when trying to output them. My best guess is its a clock problem, as the flatscreen insists on 60hz for VGA modes, and the only time I had working 320x200 and 320x256 modes was with a CRT that didn't mind 70 or 80hz vsyncs (Mediator+virge card). Is that a limitation in the gfx card, mediator, or p96?
