If you have a DVD burner, you may want to look into software like
this . I've used it with home video transferred from MiniDV (although I have to use an MPEG converter) - if you are starting with a non-commercial DVD (such as what your camera creates), you could fairly easily combine content from multiple discs into a single 5" DVD along with pretty nice menus. It would just be a matter of copying the finalized 3" DVD's to a hard drive, using a wizard to load each into the program, and defining as simple or complex a menu as you want (and no menu is an option). I used an older version to create my
Devious Tiny Disc . Granted, a license for it will cost more than a cheap DVD player, but it'd end up costing less than a bunch of those CD adapters (assuming they even work in your changer) and the 5" discs could be made pretty quickly.
