DVD Rips won't play in Surround Sound
wer:
I made an IFO to do some testing on this...
I've found two bugs in MC, which might be contributing to what you're seeing. (As I said, I don't fully understand what you're trying to say.)
The following apply when playing from an IFO backup of a DVD with multiple audio streams:
1. Audio Path displays an incorrect channel count when bitstreaming is on. When bitstreaming is on, Audio Path indicates 2ch input, even when the input track is 5.1 AC3 or 5.1 DTS. It is the Audio Path display that is wrong, because the HDMI sink indicates the signal received is 5.1, so the audio is being output correctly but the Audio Path display is incorrect. This could trick you into thinking you're getting a stereo track when in fact you are not.
2. When selecting alternate audio tracks from the interactive DVD Menu, the audio track selection does not work. Regardless of what is selected, MC plays the default audio track. This is confirmed by the diagnostics from the HDMI sink. However, this can be mitigated by using the LANGUAGE menu from the right-click menu during playback to select an alternate track. When an audio track is selected using the LANGUAGE option on the right-click menu, the correct audio track is output by MC. However, this workaround can be confusing because the language menu may just indicate "English" for both choices, with no way to differentiate between DTS and AC3.
So to recap: Audio Path channel count is wrong when bitstreaming, and audio track selection using the interactive DVD menu does not work when playing IFO dvd backups; only the LANGUAGE option on MC's right-click menu works.
The second problem I consider more serious, but I don't know how long it's been an issue, as I don't normally use IFOs. The 1st problem is an annoyance to some, but I don't bitstream either, so really neither of these affect me, but I can see them making life hard for other people.
Rocky, for you I suggest you try selecting alternate audio tracks using the LANGUAGE menu shown in the right-click menu in the screenshot you provided. That works.
Beyond that, I don't think we can make further progress with this unless someone from JRiver would like to chime in on those two bugs.
I hope this helps.

The Audio Path when Bitstreaming is not meaningful, since MC is just passing through the original stream from the disc, it does not necessarily know whats inside. The Audio Path will show the physical properties of the stream being passed to the audio device, which in "SD" audio like AC3 from a DVD is always a stereo stream which contains the compressed audio data. It has always been this way and is independent of it being a DVD.
The menu choice is driven by the Microsoft DVD Navigator, its not something we control. If that doesn't work its possible that we can't do anything about that, but i'll try to find a DVD and test it.

Ok, thanks Hendrik.
Do you think it might make sense to have Audio Path say "ac3 bitstream" instead of "ac3 2ch" since the "2ch" is usually misleading? That would both make it always correct and eliminate confusion.
Appreciate your checking the menu choice issue...

After seeing Wer's Posting about the Channel Count being incorrectly reported in the Audio Path.. I loaded my "Abbey Road 50th Anniversary DVD" and told MC27 to play it to see what the Audio Path was reporting for the various audio streams:-
According to the info on the Back of the Book the album came in and the info showing in the "streams" option
The PCM stream is pcm_bluray 96Khz, 24 bit, stereo, 4608 kb/s - Audio Path reported it as 96Khz 24 bit 2 channel from source format pcm_bluray
The DTS-HD stream is dts-hd ma, 96Khz, 24 bit, 5.1 channel - Audio Path reported it as 192Khz 16 bit 8 channel from source format dts
The Dolby Atmos stream is truehd, 48Khz, 24 bit, 7.1 channel - Audio Path reported it as 192Khz 16 bit 8 channel from source format truehd
There is also an ac3 stream which only shows up on the streams option menu
on the streams menu it's reported as ac3, 48Khz 5.1 640kbs [ sub ] - Audio Path reported it as 48Khz 16 bit 2 channel from source format ac3
Like Wer the only thing that happened when I left-clicked on the Interactive DVD Menu was MC27went into paused mode. I was only able to change streams was via the right-click streams option and using the right-click jump-to option to change tracks (chapters).
Not sure if it's supposed to happen this way - but every time I told MC to change stream the track playing paused, MC changed streams and then continued playing that track

That is not at all what I said. The interactive DVD menu mostly worked. I could navigate from page to page, I could select different video tracks, and do the other things one can normally do in those menus. The only thing that did not work normally from the interactive/animated DVD menu was selecting an alternate audio track.
From what I've seen, and what I tried to describe, is that outside the interactive menu, alternate audio tracks show up in ONE of two places:
If they are directly selectable, a STREAMS menu will appear on the right click menu, and they may be selected there. This happens if the source is an MKV file. Otherwise, if the source is an IFO, you don't get a STREAMS menu, there is a LANGUAGE menu instead and they are selectable there.
