[QUOTE=Scott;2105]I downloaded TsMuxer but that app is certainly not noob-friendly.  It looks like it wants to make me downconvert my audio, too, which I don't want to do.  I guess I need to read up more on the purpose/use of this app.
Meanwhile...I installed MPC Home Cinema and tested playing my files.  Video looked swell and the audio was working fine as well, but it played my chapters out of sequence, which got me to worrying that DVDFab had chosen the wrong movie track to rip.  I later discovered that if I chose "Play DVD" (or something like that) from the menu, that it then seemed to get the chapter sequence info correctly.
Right now I'm re-ripping Ratatouille with no compression (that should take about an hour) and will later re-rip it at DVD9 1080p so as to take an up-close look at the PQ on my computer monitor.  FWIW, my compressed DVD9 720P rip took a bit under 5 hours, which is better than I feared, since I turned off GPU acceleration and I'm working with a dual-core Athlon (about 2GHz, I think) w/2GB of RAM.  If they get GPU acceleration working, I'm hoping that I can get even better speeds, but, hey, I could kick off a movie per night to rip/compress and live with this.[/QUOTE]
Scott muxer is uesr friendly once you have played with it a few times,to use it go to the folder where your BD file is, open the folder, then drill down to the BDMV file open that, then drill down to stream open the stream file and look for the largest file there, it will be eight figures, take note of the file number.
Now open muxer click on the add button then import that one file, remove every thing but the H.256 and the AC3 files, half way down check the Blu-ray button, open the browse select where you want the muxed file to reside, click the start muxing button. 
Done, you now have one file audio and video.
