In short:

You have to choose a compression. It should have warned you with a popup. Uncompressed video is big.


More detail:

When you open the mpeg, VDubMod decodes/uncompresses it for display. VDubMod can not compress back to mpeg so you have to save your changes to an avi file and then recompress/encode that to mpeg. You could also frameserve to an mpeg encoder. This skips the avi encode but not the mpeg re-encode.

Generally, re-encoding mpeg is not considered a good thing. However, depending on the source, it may be fine for you. After all, DVD to DVDr, SVCD, VCD, etc is all about re-encoding mpeg.
