I have Nero 8, aka Nero StartSmart Essentials. When I try to burn a DVD, I go to the Rip and Burn Tab, click Burn Video Disk, and then I click DVD-Video files. When I get there and I try to add files, the only file types I can add are .bup, .vob, and .ifo. My files are all MP4s, mpegs, or AVIs. My sister thinks I need the program Nero Vision to get it to burn my files. Is this true, or is something else wrong? Also, I tried burning the DVD as a data CD, but it didn't play on my DVD player.
