Hello. If you want to keep the menus for each one then DVD Remake is a pretty easy program to use you don't care about keeping the menus but want to make your own then programs like Nerovision and TMPGEnc Author may be your friendNero.com" class="korostus" target="_blank"> has a fully functional trial version as does TMPGEnc Author 1.6. Version 2 is not fully functional.If you don't care about menus at all and want the two videos to play sequentially the DVD Shrink can do this is Reauthor mode you sure you want to do this? A lot of compression will be required to fit two DVDs onto one with a significant loss in video quality.
