Actually, home-burned DVDs have no region coding at all unless specified by the author. These region-free DVDs will not be inhibited by the region coding of a particular player. Sending a US made DVD to Australia, however, presents a different problem. The Australian player must be able to properly convert the signal of the US DVD (NTSC) to the television standard of Australia (PAL). I have read that many TVs in countries outside the US are able to handle both television standards, though, so it may not be a problem at all.
