? about multiplexing when creating MPEG-2/DVD

[HawkBoy]

I've looked at some other articles but am still uncertain about this.

After exporting to MPEG-2 from Premiere using BBmpeg, I have a file that Ulead DVD Movie Factory 2 will send to DVD without re-encoding (so I'm not losing any more quality).

However, DVD Movie Factory *does* multiplex the audio/video before burning...is this a step I should be eliminating when the file was originally encoded? Am I losing any quality by this?

(In the past I had exported to .m2v and .mp2 files, but then DVD Movie Factory didn't seem to recognize them so I started going this route.)

If I understand the question correctly, Ulead DVD Movie Factory will first split the audio from the MPeg video and then build the multiplexed VOB file.

Yeah...which I *think* is okay, and isn't re-encoding anything (because it has a separate process for "re-encoding" it goes through if it needs to, and it isn't doing that part), but I'm not quite sure *shrugs*
