I don't know about the 1084, but the 1080 i have (NTSC) could not display PAL screens complete, be it a game or app, unless i trimmed the vertical size a bit. Although more games were issued as PAL, i remember the FA-18 Interceptor running full-screen on my A1000, whereas it left a blank stripe on PAL miggies... :-)
It all comes down to what each individual wants; if you happen to do video stuff and use cameras and vcr's and genlocks that are NTSC, you simply have to stick with that..
