Don't join the AVIs. (If they aren't identical specificationswise, they can't be joined anyway.)
Encode each separately, and bring them together as one title when you author. (In TDA you add all mpg files to the same title and remove the chapter point at the joins.)
Or take the fast lane, and use convertx2dvd

mats advice is good, however if you wish to experiment, try AVI Demux. It seems to work with files that virtualdub turns it's nose up at.
