Just a little update. Made a couple more Kvobs

and both turned out awesome. One was a DVD source and I re-encoded the AC3 from 384 kbps to 256kbps, looked and sounded great. The other was an avi source so for ac3 sound I just used loaded it into the ffmpeggui from
http://www.dvdrhelp.com/tools?toolse...uthorfeatures=
and a short time later I had my 2 channel AC3@192.
I always create the full kvob, check it out for visual quality/audio sync, etc.
Then I burn a small (10 min)piece as data on a cdrw. My standalone reads raw mpeg so I can test for visual quality/audio sync, etc. on the dvd player.
3 Kvobs

=4.18 GB so should be good to go.
Now to author my first KDVD and I am figured I will use this proggy.

It is a gui for

I opened up and looks nice and simple...we'll see how it goes.
@Kwag...I reread your answer above and I beleive disabling LFE would not save final size, as you state it is the .1 in 5.1, so I leave it enabled.
I missed that in my dumb question below that. :P
