Is their anyway to make a PS3(Region 4) play a DVD (Region 1)?
Yes, you can try my method, you can try to make a region free DVD from your region limit DVD(Region 1, etc), then can play the region free DVDs on any region DVD player or ps3(region 4, etc), you can try RZ DVD COPY, it can remove region code limit and copy DVD to a new DVD disc, then you can play the copied region free dvd in your region 4 ps3. You can yahoo or google search and download RZ DVD COPY, easy to use, hope it can help you.
