Replacing DVD Audio track (how does this sound?)

[ArtOfLosingMFZB]

Hi everyone. What I am planning on doing is taking the main audio track from a DVD, altering it, then placing it back into the DVD, retaining menus, chapters, etc. Here is how I plan to do it, as of now:

1) Demux (using PGCDemux)
2) Alter the main AC3 audio track (which will involve converting to WAV, and then back to AC3)
3) Re-author (using Muxman or something similar)
4) Replace the original DVD with the re-authored one using VobBlanker to get back the original menus, chapter stops, etc.

Does that sound like a solid plan or is there an easier or more effective way to go about it? Any help would be appreciated, thanks.

Pretty much.

I have done this before and this animated guide is great.

If I done this once I've done it probably 500 times, and that's exactly the process I use.
