Thanks for the help guys, yes, the cheap multi system players are going
to be the cheapest easiest option. I looked at multi system TV's in
Brazil but as far as I can tell these step into the expensive LCD tv
realm..
LiteOn was a brand of player I found here in Europe that seemed to have
a healthy list of TV systems: NTSC-M, PAL-B/G, PAL-D/K, PAL-I/I, or
SECAM-L/L
It's a recorder so I still don't know what it would make of the
Brazilian Pal-m signal while recording, but I understand there are
options like digital top boxes, etc..
