Ok guys Ive used write image files to disk but my DVD player cant play it only my pc. The files are AVI and the DVD player is a phillips, I know it works because it played a disk after being burnt with nero. Does IMG do a multi format burn like nero or do I need different software to do it then add to the burn list, also could it be the way I lay out the multiple vids, do I need to merge them for it to play?
