I own one but I aint sure jt.
Only switch to prog scan on DVD and there all WS anyway.
I actually would not use it in prog scan for off air broadcasts as the flicker is annoying, which to be fair is pointed out in the manual.
The TV is has a great picture especially when playing prog scan DVD. It will of course do PAL and NTSC prog scan which the tosh cant. You will need a suitably equipted DVD player (I have a Harman Kardon DVD25 firmware upgraded to give PAL prog scan )
to get PAL prog scan and the results are great.
I also use it with a digital decoder for freeview, this also gives a great picture, as good as the Sony IDTV I had before.
Hope this helps.
I got mine from Bennets online for £1043 inc del.
