I have edited a dvd in pal format that is going to be used at a conference in Brazil. apparantly they use the PAL-M format which is different to the standard PAL system we use in Australia. in theory my PAL dvd should be playable in a dvd player over there, but I am wondering if there is a way i can convert it to a PAL-M format as a precaution (i can export it from premier to most formats but I don't think premier support PAL-M at least my copy doesn't.

Any ideas or suggestions?

The PAL-M/B/G/I standards usually indicate a change in the subcarrier frequencies.
EXCEPT Brazil seems the ONLY country to use a non-standard PAL format.
Instead of 625lines @ 50Hz, they use 525/60 instead.
A kinf of halfway house to the 60Hz rate of US broadcasts, while keeping PAL quality.
