progressive scan on denon 3800 & region coding

Simple question on this really .In the reviews of this machine in the mags they all say the progresive scan works well yet the machine does not yet play pal prog scan (firmware pending) and it apparently does not play ntsc discs (region 1) either ...so how do they know ???

I have just ordered one of these and i hope that the firmware fix is soon and hopefully chroma bug free and rce compatible too .I have checked all my region 2 collection and they are all in pal format not ntsc ...somebody help me please !!!

 

They would probably have had to use some of the Region 0, NTSC music type discs

Just a thought...
