Greetings, My apologies in advance, this is not my field, I am working on a 1 time project. I filmed 4 days of presentations. I edited them using Microsoft Movie Maker. I saved them as windows movie files. I burned them to a DVD as data files. They will not play on my home DVD player. I have to make about 20 copies which were sold, and I need them to play on home dvd players. Any suggestions would be greatly appreciated. I bought nero ultimate package V6 today, hoping that might help.
