I can't. It's a DVD that needs to be recompiled using Recode to fit on a single layer disc. I guess I could use DVD Shrink and see if it burns with that. If it burns OK tonight with the older version of Recode (that is, if the Recode version is in fact updated - Nero is skimpy on the details of what's changed), then I guess that's my answer. If not, then I'll give it a go using DVD Shrink instead...
