Hey, I have that Jaton and it has worked great. I don't have a progressive scan TV, but I plan on having one in the future. The player can be changed to send either an interlaced or a progressive signal to the TV.
So far it has played Region 2 Pal, Region 3 NTSC, Region 1 NTSC, and mp3's burned onto a cdr. I haven't tried anything else yet. It's been fine with Episode 2 and Monster's Inc, which are two movies that have given other region free or hacked players problems. It's been a great player and I would recommend it to anyone.
Out of the box it wasn't region free, so don't freak out like I did. I just had to do a remote control mod and it's worked fine since then.
I purchased mine from HKFlix.com, but it is pretty much the same price wherever you buy it. I think HKFLix and AZN films both ship from CA, so I may take a few days depending upon where you live.
Hope that helped a little.
