I don't have a portable DVD player, but in regards to your question about the widescreen dimensions, you might want to make sure that the player has an aspect ratio control feature that will allow you to watch the movie in 4x3 mode. If not, the player will either chop off the top/bottom of the picture or it will stretch the image to fill the screen.
I have the Eran Trece DVD from Andy and it is very well done. Unfortunately I couldn't get any of his other Chan DVDs to play in my player so I had to return them to Andy. He was very gracious about this and explained that the media he uses is incompatible with a handful of players.
Hi Steve,
Hey, thanks for the information. I think I'd better get in touch with him and see if the disks are compatible with the player I plan on buying.
