What about trying this workflow, instead?
Capture -- high bitrate MPEG, I'm guessing?
Edit - Womble MPEG Video Wizard, export as MPEG file
Re-encode (Mainconcept MPEG Encoder) -- good software
Author (Ulead DVD Movie Factory 6) -- I'd suggest Ulead DVD Workshop 2 or TMPGEnc Authoring Works 4
Burn (ImgBurn)- Good choice
Are you re-encoding because you've captured your MPEG at a high bitrate?
And maybe you're wanting to really fill up a disc with max compression?
Or you have complex content like wrestling, NASCAR, etc?
That's the only reason I can see for this method.
