Movie length/time is wrong when playing VOB

[nmiller0113]

That subject was vague but hopefully I can clear it up here. I'm not exactly a newbie but this may be a newbie question and I don't know where else to put it.

Let me first tell you what I'm trying to accomplish. I'm trying to rip a DVD extracting only the Main Movie and the AC3 Audio and eventually get it to an MPEG. This is for streaming my movies to my Xbox 360 Media Extender.

Here's what I've done so far. I've ripped the DVD with DVD Decrypter to an ISO. I then used Daemon Tools to mount the image and opened DVD Shrink from there to strip out everything I don't want. I then shrunk it down to about 75% and encoded it. The output from DVD Shrink was 1 Large VOB. I then did something I was told to try out which was just changing the filename extension to .mpg to make MPEG Players play it. That is the format I need and I was told that changing the extension did it since MPEG-2 and VOB's were essentially the same.

Well that works fine, kinda, and the movies look great. Here's my problem. The movie shows up as being only 21 mins long when it is indeed 1 1/2 hours. So it kinda pisses everything off when I try to search through the movie. I also tried just leaving the extension as VOB and using my DVD Player to play instead of my Windows Media Player and I get the same results.

I'm sure that this is just some amateur move on my part, but can someone tell me the one step I'm missing that's causing my times to be all wrong.

Your assistance is greatly appreciated. Thanks!

How many audio stream do you have on your vob?
Have you tried to use DGIndex to demux your VOB and remux it again (You can try ImagoMPEG-Muxer here:http://www.videohelp.com/tools?tool=ImagoMPEG-Muxer)?

I only have 1 audio stream, AC3 English, and that is all. I will try one of those tools you were talking about. Just out of curiousity...do you have any ideas of what causes it and why one of those tools would help? I'm just wanting to understand better how things work. Thanks!

Well... VOBs and MPEGs have different muxing profiles... you may have mixed up time stamps... have you tried to put the extension back to VOB? maybe the wrong extension is confusing you player?!?!
Anyway... demux the vob/mpeg... and mux the files back using the right profile...

One other possibility is that you don't have the full audio track... can you hear the sound after passing the 21st minute?

sorry for my english :)

Let me first tell you what I'm trying to accomplish. I'm trying to rip a DVD extracting only the Main Movie and the AC3 Audio and eventually get it to an MPEG.I believe you could accomplish this in just one pass, by using DVD Decrypter in "IFO mode", set to create ONE .VOB - and select "Stream Processing" and check only those streams you want to retain (Video and .AC3) and save as .VOB - Then change the .VOB extender to .MPG...

The movie plays just fine all the way through all 1 1/2 hours of it. The funny part is in the player it shows only 21 mins and when the movie gets to 21 mins it continues to play even though the player thinks it is at the end of the movie. I've tried it on multiple players and they all give the same result. I've tried as a .VOB or as an .MPG and I get the same results. Like I said the movie, both audio and video, play just fine all the way through...I only see a problem if I try to search ahead or just click ahead to a spot further in the movie. That is where the incorrect movie length issue will cause the player to either lock up or completely stop the movie.

I am more than willing to try to demux and remux the movie but isn't that what DVD Shrink is doing? Like I said...this whole thing is really new to me so I don't know. I've read about some other mux/demux tools and it looks like I'll lose my ACS 5.1 Channel track to stereo, but I could be understanding this incorrectly as well. Thanks for listening!

Do try the simpler method I've described - It's not only changing ".VOB" to ".MPG", it's properly ripping the files...

[nmiller0113]

I may not have mentioned that previously, but I did already try that. I will try again just in case I biffed something. Maybe I have a setting wrong.

The only reason I'm going about this is because I want to get the files playing on my Windows Media Extender on my Xbox 360. It can play AC3 audio so I definitely want to keep that. It can also play .mpg files, so that looks like the route I'm going to take because the .WMV encoding has been nothing but crap in my opinion.

Before that I was just making ISO images of all my movies with Decrypter and shrinking them a bit with DVD Shrink...still remaining an ISO image. I can get those to play locally on my Windows Media Center no problem...it is a limitation of the hardware on the extenders as to what it can decode and that is the reason I'm doing this. Thanks!

[nmiller0113]

So I tried it again just using DVD Decrypter and had the same results. Maybe someone could test this out and see if they get the same thing and it isn't something I'm doing.

If anyone has any ideas that would be great. If it is going to take doing a demux/mux, I'm all for it, but will I lose my AC3 5.1 Channel Digital Audio? Thanks all!

No... you don't loose the AC3 5.1 at all... the streams will remain exactly the same.

edit: if demux/remux doesn't work... maybe you'll need to run AC3fix on your AC3 file.

I've tried it on multiple players and they all give the same resultIf you haven't already done so, try the (freeware) VLC player...
