Yes, I'd like confirmation that what I saw is true with PowerDVD although I am confident you'll have the same results.
OK, I can confirm what you experienced, i.e. audio is NOT grayed out for the deleted/alternate scenes.
Here is a summary of what I found with just the output from AnyDVD Ripper in AnyDVD 6.3.0.9:
1. Previews/Sneak Peeks that play when the DVD begins and also in the special features menu: audio plays but selection is grayed out.
2. "Making Of" in Special Features: audio grayed out, subtitle selection OK
3. PE Trauma Tales in Special Features: audio grayed out, subtitle selection OK
4. Trailer: audio grayed out
I ran the files through PGCEdit and it didn't make any changes that fixed this. It appears that there is an audio stream 0 listed for each of the sneak peek titles, so the issue doesn't seem to be that it isn't listed as present...
In one of my previous messages, I indicated that all was was well with the original DVD (still true) and a DVDFab fulldisc rip. I went back and looked at the DVDFab output and found that the Sneak Peeks on the Special Features menu not only have audio grayed out, but the audio is missing entirely! All other selections, including the sneak peeks at the beginning of DVD play work as expected. A DVDFab clone mounted in Daemon Tools works fine in all areas, as I expect an AnyDVD/CloneCD should.
I'm begining to feel like Webslinger - that it is better to just clone and play and give up on ripping and trying to fix the protection...
OK, I'm done experimenting with this title.
