I used dvd shrink to copy a dvd to my HD. I have Nero and the directions on this site to burn a backup with nero says to go under "DVD" then "DVD-VIdeo" my options under "dvd" are DVD-rom iso,dvd copy, dvd rom boot, dvd rom udf, and dvd rom udf/iso. I tried to burn it under dvd-rom iso, but my dvd player is not recognizing the disc. my player has recognized burned backups before.... what if my nero has no dvd-video.....should I use the cd-r drive and do a video cd????
