There are a few threads about this, but they haven't been answered.
Can MP play .vob files with LPCM sound? (Vista MCE can)
I've tried to put the file in a VIDEO_TS Folder, but then it just wanted to play the DVD currently in my drive...
Renaming .vob to .mpg makes the video work, but no audio.

Graphedit shows audio going through DScaler and then through AC3Filter when playing with WMP Classic
Graphedit shows audio going through through AC3Filter when playing with MP

The graphs are different, but there is no way to change it to the right one it seems. When I disconnect all links to be able to reconnect again MP stops playing and the graph is disconnected.

Did anyone get this to work or did ya all just convert the .vob to something else?

I only have to files with LPCM sound and will just convert them.
I can imagine this might suck when you'd have 1080P streams with LPCM sound.
