Well, first the required statement:
DVDs made from downloads look like crap 99% of the time. This hobby is deteriorated every time somebody adds these low quality sets to circulation.
Anyway, you are using the DIVX codec. To not see the logo, remove the official DIVX junk off your system. Use the XVID codec package, as it plays DIVX too, without the logos.
And remember to restore the overscan when converting to MPEG. See the guide that I wrote here in this forum, refer to the sticky in the VIDEO TECH area, the CPS DVD creation tips list.
