hmm I wonder the issue has something to do with audio or subs overhead. I had first 2 hit target size, well good enough 4369 and 4375 MB, but since I've gotten 4225 MB and 4464 MB with the defualt DVD5 size of 4369 MB. Lots of variance and I can't see anything uncommon between them. The 4225 and 4375 results had ac3 audio, while 4369 and 4464 had DTS audio. All had 3 subtitles except 4375 MB only had 2.
