Ripping a DVD to MKV

[zinga]

Hi
I have a DVD with multiple audio tracks and video angles. I want to rip these into an MKV file, retaining pretty much full quality. I've tried GordianKnot, but it seems to want to resize the clip, whereas I want to keep the original resolution.
Is there any program which can do this? I don't mind manually doing some things...

Also, I've tried splicing the VOBs in the main PGC using AVISynth, but for some reason, I don't get the correct length clip.

Thanks in advance.

I'd suggest MeGUI. Follow the link in my sig for a walkthrough of what you want. In the case of multiangle files, simply use DVD Dec in IFO mode and select only the angle you want.

Okay, thanks. I'll try it...

A quick question: doesn't multiple angles mean multiple video tracks?
Because the DVD (with 2 angles) is 2:47:15 long, but when I use DVD Decrypter to extract one angle, it's 1:24:20 long, which seems to be half the length...

Thanks again, in advance.

Hmm, it seems that they ARE multiple video streams, however each angle is of a different length! (don't know why it says the whole DVD is 2:47:15 long).

How would I mux the video streams into an MKV if each angle is of different length? Is this even possible?

You can mux them exactly the same if they are different lengths, there's no difference in the procedure.
The differing lengths is possibly due 'freeze frames' or something similar in the DVD - are there any slideshow like moments in the middle of what you're trying to rip?

So will each video stream be of the same length after encoding?
Because if this is not the case, then wouldn't there be audio/video desync?
Anyways, thanks for the explanation - I'll try to encode the video and see if it works...

no, each stream will stay the same length. If the audio runs out before the video, there will be silence. If vice versa, there will be a black screen. Nothing tricky like changing lengths or anything :)

Hmm, also I just demuxed the AC3 streams - each is 2:47:15 in length! I'm really confused now: I have two video angles, the first is 1:24:20, the second is 1:23:00 and two audio streams, both 2:47:15 in length. How do these combine in sync?

A quick question: for the demuxed AC3 files, they have a delay. Just wondering, if it says DELAY 33ms for example, does it mean that the audio stream starts 33ms BEFORE or AFTER the video starts playing?

I asked before: "are there any slideshow like moments in the middle of what you're trying to rip?".
As for the delay, I'm reasonably certain it means the audio starts 33ms after the video. In any case, if you have to enter it anywhere, you always enter (+)33, ie as its written in the filename.

What exactly does "slideshow like moments" mean? I haven't seen the entire DVD so I can't really answer that.
Anyways, this is what I have done so far:
1. Demuxed each angle using DVD Decrypter
2. Ran each angle through DGIndex, creating a D2V file and demuxing the AC3 tracks. Confirmed that the tracks demuxed from each angle is identical (ie the two tracks from angle 1 are identical to the two tracks from angle 2)
3. Opened the IFO file of each angle, and all AC3 tracks in MPC to confirm their length. I also opened the original DVD in MPC to check its length.
The correct length should be 2:47:15, but the video streams aren't that length... Perhaps DVD Decrypter isn't extracting the entire video? But that's also weird because the DVD is 7.82GB in size (the main PGC is 7.09GB) whereas the extracted angle 1 is 5.93GB, and angle 2 is 5.84GB.

Anyways, thanks a lot for helping me this far - sorry for being a n00b...

Oh, I also checked the start and end of the extracted VOB files - the appear to be identical.
Also the chapter file goes up to 2:47:15...

Sounds like a strange DVD - try posting in the decrypting forum about it with all the info on it's title, region, PAL/NTSC, etc etc and see if they can help.

Okay. Again, thanks a lot for your help.
