Final Avi Size smaller than Intermediate files

Can you please post your file sizes for all *.avi and *.mp3 files. Also, did the end result come out fine? If it did, I wouldnt really worry about this error message, but I can't be sure unless I can see the file sizes. Thanks.

I had the same warning but payed no attention to it. I noticed though that it only gives it to me when I do a manual IVTC and not the forced film from DVD2AVI. Though I can't confirm this as Iv'e only seen this warning twice. But both time i had to do IVTC with AVIsynth. Maybe that had something to with it?

I delete everything & reinstall gknot then everything work fine. Thanks for all your help anyway. Gknot is more fun than xmpeg4.5 but I wish the wait time is shorter for both program, instead 5 -6 hrs.
