You can burn a .img file by first loading it onto a 'clone-drive' ( available from clonecd) and copy to a dvd using clone DVD. Make a recovery point ( in XP ) first because you may get a problem with the sound after instalation and need to undo it. I've been told that you can also just change the suffex to .iso and that will work. ( never tried that).
I assume region means USA !. Almost all TV related equiptment sold in the USA is only sutable to play NTSC, you don't have anything else so why include the option for PAL? In Europe we have always had more than one TV system ( PAL-SECAM) and because we also import direct from the USA our systems are built to play them all. The only way you can play a PAL will be to convert it in someway to NTSC. RIP and rebuild.
