I'm having a tough time deciding which authoring tool to go with to author an MPEG2 file to DVD format. There seem to be many choices: Sonic Foundry's DVD Architect TMPGenc DVD author DVDit Roxio's DVD Builder Ulead's DVD Movie Factory nerovision and so on. So what experiences have you had with these. Are there any that you would recommend or not recommend? I should say that I'm not really looking for professional quality (more for something that is easy to use).
