The use of the region free codes cannot damage your player or lock it forever! If this in a rare occasion happens, it is easy to recover from it by re-initiliaze your player from the setup.
- Don't ask if your player/recorder can be made region free using this code, just try it! Again, you cannot damage your player using this code.
I removed a list from my site which players/recorders where known to be supported to prevent the "does it work with my player?" questions. However I would appreciate if you succeed to post your player type.
