When I post for help or direction in a forum & then accidently find the answer to the Issue myself, reguardless of how dumb it may make Me look I follow up with instructions as to what worked for Me. 
In this case I was trying to take 1 of My DVD'S & convert it to AVI with Winavi .

After clicking on Winavi's Any2Avi Radio Button I would navigate to the folder where I had saved the Decrypted DVD files & select all the files (Bup's,Ifo's,AVI's) within it & hit convert of course Winavi would quickly throw up the errors I was seeing Since Winavi clearly shows on it's Gui that it'll convert VOB's to AVI & I was selecting all the files (Vob's Ifo's & Bup's).
At any rate I was able to convert DVD to AVI in the manner below

I've found that if I only selct the Vob's & then select to convert,Winavi will indeed convert the DVD to AVI
Hope this helps the next guy who might see this error.

Thanx for the link Madison22 I'll check it out,but since I figured out how to convert DVD over to AVI with Winavi I will probably stick with it.
Besides Winavi converts so darn fast!
But thanx all the same.
