i have episodes of my favorite show and i converted them to .vob .bup .ifo files and i want to burn them on a dvd so i can watch them, but each episode is broken down into 15 sec segments. so when i try to put 4 episodes on one disc in nero it only burns the first 15 secs. is this because they all have the same name or what. please help me or give me a guide to put my episodes on to a dvd. they are originaly on my computer as .rvmb files. please help i don't know what to do.
