I am having an issue with compiling a dvd of .vob files.
Each vob file imported into the project seems to drop in length, when I go to add chapters it looses about 10 secs of footage of the end of each title.

I have checked each title source length, and I am certainly loosing some length in MyDVD.

your help is appreciated

This is really bothering me, I have spent days making three compilation DVD's, and they all have clipped ends to the titles.

Can anyone suggest a solution.

Am I going to have to convert all my sources to mp4?

Is there a technical reason why MyDVD deals with vob files this way and not other formats.

I have noticed that Disc Copier does a similar thing with start/in and finish/out points when you edit a vob - it is always a few seconds away from the point set and displayed in the preview window.

What is the source of these vob files? I know they are on a DVD but what was used to make this DVD?

I used DVD Shrink, then I used Disc Copier to change the "in point".

How about creating an mpeg out of the video folder set (the DVD) using Disc Copier? Then bring in that mpg file in Videowave and do your trimming/splitting/editing there.

I have edited the in/out point in Disc Copier, and I have all the files the way I want them, but when I import them in to MyDVD the length of the clip changes (-10 or -30 secs).

My overall project desire is to many hours on one disc. I have a conference of 14 sessions, each between (45-75 mins). I have managed to get them on 3 discs, menus and everything.

I thought the whole project was finished, until I tested them and some of the VOBs finished prematurely, it would have been ok if I had some trailing black vid at the end of each session, but they are cut rather abruptly. - So precision was most important.

If I have to convert them back to Mpeg again I will have to compress them all over again, and the resulting video quality will be terrible.

Since I first posting I have added black video to the end of each clip, by joining clips using VobEdit and creating a new ifo using ifoedit, I thought I had it cracked...

but now I can import into MyDVD and all is welll, I have much room for error in clip length (with my added black vid) - but now MyDVD hangs on 1% encoding.

I have exported the resulting joined (vob) DVD through Disc Copier, and then even through DVD Shrink again to eliminate any encoding/compliance errors. Same Problem.

Any Ideas?

Thanks for your help.

-----------------
Not a solution but interesting: I just tried MyDVD LE 6.1.1 with one of the joined files and it output the file OK

James (post #3 above) asked you what is the source of the DVD. DVDShrink is the medium that you used to generate the vob files from the source. So what is the source?

Opps, ok sorry.

DVD ripped

I have a dvd ripped which I import the VOB into MyDVD, it says "please select movies to import" -
Movie 1 is 51:57:00 but when I edit chapters it says it's only 51:11:10

thanks

Perhaps if we ask a different way.  Where did you get the original, original, orignal video files?  Were they on a DVD that you bought, was it something that you recorded, was it something that someone else recorded? Was it downloaded from the internet, Was it something that the original producer copyrighted?  Is it covered by DRM in the US?

Why are you using those other programs and then trying to use this one?  It is pretty hard tracking down a problem and would be pretty easy to blame it on one of the other programs.  

If you are trying to copy a copyrighted and DRM protected DVD, this conversation stops here for potential legal issues.
