Okay, for the past three days I have tried the following software to get a downloaded ISO file to function with a DVD player; ImgBurn, Nero StartSmart, Xilisoft and currently Alcohol 120%. At this point is there any software that will simply convert a ISO to AVI. I have software to burn AVIs to DVD....
If this is an image of a DVD movie, open it in DVD Shrink (File > Open Disk Image). If it opens without complaint, click 'Backup' and save to a folder on the HDD. Burn the VIDEO_TS folder with ImgBurn.
