I am new to this site and making DVD's! I have made a few great DVD's but am running into a problem playing them on all DVD players. We are sending them to sponsor's of my dad's racecar so, we can't send them and just hope they work. does anyone have any suggestions to help? I am using an HP Media Center computer (brand new and they said that this computer would be great for making home movies!)... I am using Arcsoft ShowBiz to edit the movies... should I be using another program? Any help is greatly appreciated. Thanks so much!
