An .avi is the most universal format and will run on any Windows OS
computer. But it is the lowest quality, largest file size and recently
Microsoft took it off the 'preferred format' list. I generally use MPEG
level 1 videos, as they are almost universally usable on all machines, have
fairly good quality and file size. The key to good quality is to render the
videos at a large enough size for the size you want to view at (sorry cannot
remember the render sizes off the top, but think 1024x768). The file size is
a bit larger, but the playback quality increases even more.
If you know the files will be run on systems you know, look into MPEG level
4 files. The quality is much higher and file size even smaller. But this
format is not going to work on many computers as they have not been updated
with the newer WMP.
