Very often a DVD video disk has small opening before the main movie, for example some logo or warning about 18+ or warning about copying is forbidden, and so on.
Mpv plays only this opening and then finishes immediately. It doesn't play the main movie.
Is it possible to fix such behavior, please?

And may be this is not bad idea: let mpv to play VTS_0x_0.IFO files? Now It plays only VIDEO_TS.IFO
VTS_0x_0.IFO files are the 'headers' of separated titles on DVD disk. Now if we try to open VTS_0x_0.IFO with mpv it searches the main VIDEO_TS.IFO and plays it, if VIDEO_TS.IFO doesn't exist mpv reports about it end exits.

Can you tell me how exactly you're trying to play the DVD?

Perhaps try something like this command:

mpv dvd://0-5

That would play tracks 0 through 5 on the DVD. You can use < and > to move through tracks in the playlist. What you may be doing is only playing the first track somehow.

I'm playing the DVD this way: I have Windows and the VIDEO_TS folder on my disk D:
This folder was previously copied from plastic round DVD disk from market :)
If I want to see the movie I type in my command prompt:
C:mpvmpv.com D:VIDEO_TSVIDEO_TS.IFO
or
C:mpvmpv.com D:VIDEO_TSVTS_01_0.IFO

• results are the same, for example:

[ifo] .IFO detected. Redirecting to dvd://
[ifo] There are 5 titles on this DVD.
[ifo] There are 1 angles in this DVD title.

and the main title starts. If DVD has very little very first video about prohibitions or with some logo the mpv plays only this little part, not the main title, and quits.

And if VIDEO_TS.IFO doesn't exist mpv can't open VTS_01_0.IFO file.
I know this is the second question. Is it possible to enable playing the folder with only VTS_01_0.IFO and VTS_01_1.VOB - VTS_01_6.VOB for example? In short words I want play the folder consists of only one title (track).

Try dvdread:// instead of dvd://.

dvd:// 'should' work and is in theory preferable, but there's nobody around fixing the bugs in it, so have fun.

Yes! I have success!
C:mpvmpv.com dvd://2 --dvd-device=G:DVDHome

• plays the title what I need!
  Thank You very much!

But It will be very useful If anybody let mpv open .IFO files belongs to separated tracks. In my case let do this:

C:mpvmpv.com G:DVDHomeVTS_03_0.IFO

Now if I type this command mpv opens VIDEO_TS.IFO instead and plays track 0 then quits.

Oh, you've always played .ifo files directly?

Point it to the directory with --dvd-device=path and don't play ifo files.

Yes, I see if I type:
C:mpvmpv.com dvd:// --dvd-device=G:DVDHome
then mpv plays immediately the main title (track 2), not warning (track 0) and not logo (track 1)
Many thanks!

But If such files as .ifo exists It's possible to make association to mpv.com
And It can't play VTS_0X_0.IFO, redirects to VIDEO_TS.IFO and plays it in bad way - quits after first track, not continues.
If I point it to the directory with --dvd-device=path I see this:

libdvdnav: Using dvdnav version 5.0.2
[dvdnav] Selecting title 2.
[dvdnav] DVDNAV, switched to title: 3

If I play ifo directly I don't see dvdnav!

And curiously If I use
mpv.com dvdread:// --dvd-device=path
instead of
mpv.com dvd:// --dvd-device=path
then dvdnav doesn't appear and directory plays in bad way - only 1st track and quit.
So dvd:// much better than dvdread:// !!!

Yeah, dvdread:// plays the first title by default, while dvd:// plays the longest by default. Also, dvdread:// is often broken with DVDs that try to play DRM tricks.

Oh, I discovered right way!
C:mpvmpv.com dvd:// --dvd-device=.
If I associate this command with .ifo files I get success - dvdnav!

Last build still doesn't play any .IFO if the VIDEO_TS.IFO is missing in the folder.
Is it possible to play IFOs without this main file? Theoretically, I mean, It's possible..
I imagine, it would play all .VOBs with the same index, for example VTS_05_1.VOB, VTS_05_2.VOB, VTS_05_3.VOB, VTS_05_4.VOB (if VTS_05_0.IFO opened).

Not sure what exactly is failing how exactly. The things that open e.g. VTS_05_0.IFO don't explicitly check for VIDEO_TS.IFO; that must be libdvdread. Dubai duty free shop price list pdf.

I imagine, it would play all .VOBs with the same index, for example VTS_05_1.VOB, VTS_05_2.VOB, VTS_05_3.VOB, VTS_05_4.VOB (if VTS_05_0.IFO opened).

Like mpv VTS_05_*.VOB?

If we open VTS_05_1.VOB then mpv plays only VTS_05_1.VOB, it's clear :)
If I have in one folder VTS_05_0.IFO, VTS_05_1.VOB, VTS_05_2.VOB then I can play VTS_05_1.VOB and I can play VTS_05_2.VOB but I can't play VTS_05_0.IFO.

I see in my console:

G:DVDHell>C:mpvmpv.com VTS_05_0.IFO
Playing: VTS_05_0.IFO

If VIDEO_TS.IFO exists in the folder I see:

Well, .ifo files can't be read natively. libdvdread has to do that. mpv merely passes the directory the .ifo is located in as device to libdvdread, and sets the right title (parsed from the .ifo filename). libdvdread expects a standard DVD structure, and if it doesn't find that, it fails.

mpv can play the raw data too (by playing VOBs), but that's it.

What 'right' title? If I open VTS_05_0.IFO then mpv doesn't play fifth title! It plays the first title and quits immediately after this title ends! Or if I point it to directory (dvd:// --dvd-device=.) than mpv plays the longest title (title with longest duration) and libdvdnav appears in the console output.
I must point it to the title directly in command line: dvd://5

And I am interesting what does it mean 'Add support for opening DVD and Blu-ray directories directly' in 0.6th release description? What is the difference between I already saw and I don't see yet?

If I open VTS_05_0.IFO then mpv doesn't play fifth title! It plays the first title.

Well, it should. The behavior should be the same as dvd://5 --dvd-device=yourpath.

dvd://5 --dvd-device=yourpath

Sorry, that's wrong. In this case, it's dvdread://5 --dvd-device=yourpath.

Sorry, I was mistaken :( Now mpv plays the right title, not only first. This bug is gone. You are right!

That's great! Are there any problems still left?

Yes :) There is a problem: when we open VTS_05_0.IFO we watch the title 5 which physically stores 'in' VTS_06_0.IFO and VOBs (because titles numbers start from 0 and vts numbers start from 1)
So we can not open the last .IFO It's NAME points to nonexistent title :)
