Is there a list of which movies from Homg Kong Legends are really R0. I know of a few:

Drunken Master
Iron Monkey
Black Sheep Affair
Snake in Eagles Shadow

any others?

I believe Magnificent Warriors is actually R0 as well.

but they're still PAL aren't they?

Yes!

. . .

If they are PAL and you have a region free player how does that effect the picture on an American Television. Even if you dvd player is NTSC to PAL and vice versa does it still affect how the picture will look?

From what I've seen if your DVD player converts PAL to NTSC the aspect ratio will be way off. A 2:35 movie will look like a 1:85 and a 1:85 will look fullframe. This is the case with the cheap Sampo and Odyssey players.

I have an APEX 500W, and it works great with Drive. Drunken Master is already messed up but it does the conversion fine.
