Stripping & Using Only DTS Stream

[old-hack]

Wondered if anyone has tried this and what the steps might be. I'm working on a DVD that has DD 5.1 and DTS. I'd like to strip both but the resulting rip is too large for a single DVD+R. I'd like to strip the DTS stream only, which I've done, but can't activate the stream without the menu system. How can you set the DTS steam to be active without the menu system so it automatically plays during playback?

run it through SmartRipper, File Mode and remap the DTS stream.
that might work.

1) Use Ifoedit and open the VTS_XX_0.IFO file.

2) In the top box hightlight VMGM_MAT

3) In the bottom box scroll down to address 00000104 (which is VMGM audio attributes)

4) Double click on that line and change the table to the appropriate settings for DTS or DD.

5) Save the file.

I tried editing audio information using IFOEDIT. First the VMGM_MAT field is in the VIDEO_TS.IFO and not VTS_XX_X.IFO. Second, after changinG values to match existing DTS values and burning on RW media, the audio completely disappeared. Got lucky tho on the video I was using. I stripped the movie and left all of the audio streams in it. It was small enough to fit on one DVD and you can use the remote to change audio streams and subtitles during playback. Of course this isn't the solution for longer running DVD's. Was someone successful in getting the DTS audio to work using this method?

Well it seems that if you strip out everything audio related besides the DTS track, then that will be the audio track the movie uses. When I do that my player automatically selects the audio track that is present on the disc.

By far, the easiest way to do this is to use DVD Decrypter in IFO Mode.

Stream process all the tracks except the DTS. Select the DTS and tell it to remap to 0x80. That will make it the default. Rip it and tell IFO edit to make a new VIDEO_TS.IFO file.

And, for the record, just because its the only audio stream doesn't mean a player will automatically select it. Found that out the hard way.

Ah, I must have a "smart" one, hehe. Thanks Cole for your post.

You can edit the command for the main movie PGC and insert a precommand (using IfoEdit) to set the audio stream. This is sometimes less trouble than remapping IDs, and might keep the audio menus working. Before doing anything, backup your IFOs (using the IfoEdit menu command to do so). Add a new precommand to set the audio stream to n-128, where n is the stream number. So if your DTS stream is 0x88, then you want to set it to 0x88-128 = 8. If you see other commands that change the audio stream, put your command after them -- or just change them to do what you want.

You have to click out to something else and back in to the PGC to see the change. If it looks good, save the IFO and continue. If not, just quit IfoEdit and start over.

You can do the same thing to select subtitles, but there's a wrinkle. You have to set the value to 64+n-32. The n-32 just changes 0x21 to 1. Adding the 64 turns the subtitle ON. Otherwise it's selected, but OFF, so it doesn't show.
