Ripping DVDs
 

How can I rip dvds into a single file? I have several projects burned in a dvd format to disk. So far, whenever I take .vob files from disk I get some green pixelation between the seperate .vob's. How can I fix this?

if you can find dvd decrypter posted anywhere, it'll combined the vobs into one file when it rips (if you select the right option).. post back if you find it (someone else seemed to find it recently although I thought it was purchased by macrovision and taken out of commission.). of course, you still need to observe all copyright laws w/ any dvds you have.

Thanks. These are all my projects. I have DVDShrink. There is an option to create just one file.

I'm having another problem that has been really frustrating. Anyone know how to copy a disk that has been written in an open gop format? I have some older disks that were created by a sony dvd recorder. Whenever I shrink or decrypter them, the created .vob file is the correct size but only plays for about 30 seconds before stopping. Even when I import the file into Premier, it is only about 30 sec on the timeline and as I play it through it will jump to spots throughout the course of the show and then end.

Any ideas?

which model sony dvd recorder?

Its kind of humorous...... We have the 2003 Heisman trophy winner Jason White and The NBA Commissioner Dave (David) Stern on this one thread. Dvinfo.net is bringing in the big dawgs now..... :-}

You see there is life after the spotlight. Trying to finish this highlight reel before the start of the 07 season. haha.

The player is a sony RDR-GX7.

I just tried to copy and paste the .vob files from the disks to my harddrive thinking that would solve the problem. I then rename them to .mpg. And I get the same thing.

There must be something wrong with just rename the files? But I have done this before with other disks created by encore with no problem.

I have recently encountered the exact same issue. My client gave me a mini DVD, video filmed with a DVD camcorder. The footage was about 15 minutes long (he told me) and when copied to the hard drive, the file size was right... but it only played back the first 30 seconds - that was the length displayed by several players (WinMedia Player, Classic Player), and when imported into Premiere, it also played only the first 30 seconds.

Long story short, I fixed it with MPEG Streamclip, it has a feature called "fix broken timecode". It actually detects that the time code is broken and gives you the suggestion to fix it. Same software will also join your files. Just Google it, it's freeware.

interesting..I've ripped probably several hundred disks I've burned on the same recorder (dvd transfers) and have never had any issues. I've used DVDLab to author, and it does give a warning about open gop format, but they all play fine. maybe the stream fixer will help (theres one in dvd lab pro too, but I've never needed to use it). post back what happens when you fix the stream.

MPEG streamclip detects the breaks and fixes them. I save the file. It will only play in WinDVD but gets alittle jerky about every 30 secs or so and skips around like I've said above in Premier. If I open the file again in streamclip, it says the timecode is still broken.

Dave, what are you using to rip your disks?

I don't think the person who did these burns used any dvd authoring software. Just exported from Premier 5.1 to the sony. Possible that there is no timecode at all?

It is working fine. MPEG Streamclip did the trick. I had to correct the timecode of the .vob and then convert to mpg. Thanks everyone.

an old copy of DVD decrypter...since these dvd's are all ones I've created out of non-copyright source (e.g not network programming or similar), I am ok w/ copyright.

I typically rip them into one single program stream for the entire disk, trim the ripped stream (mpeg video wizard), then author with those (dvdlab pro)...
.

I'm still having some problems with ripping some disks. For some reason in certain parts I'm getting jumpy/laggy/skippy video. From the disk they play fine, but get jumpy in the same spots after shrinking.

I have another that plays fine. But when I shrink it I get a lot of green blocks across the screen and then the green goes away and it is just blocky.

Any ideas? Its seems that this ripping is very unforgiving.

that's odd... if the disk plays ok, it's probably not the ripping itself (e.g. copying from DVD media to your hard drive) that's the issue, but something else.

yo mention shrink..do you mean dvd shrink? If so, and you're using shrink to copy a dvd, most likely it's re-encoding the disk. in which case, it sounds like its something in the mpeg stream.

I woudn't think you want to re-encode the materials though.

what process and software and what steps are you using to do what you are doing?

I have tried DVD shrink and DVD decrypter with the same results. All of the settings are at default.

The video will stop at certain spots, the audio will continue, then the video will snap to where it should be. Here's alittle tidbit. If I autoplay the disk, the video will play fine throughout. If I play the individual .vob files from disk, they will glitch.

but VOB files aren't intended to be played directly.

what happens when you rip the DVD w/ decrypter in IFO mode.. on the stream tab, you can select either stream or demux ... when you play the resulting mpeg2 file on your PC does that skip as well?

DVDDecrypter is hacker tool to remove protection from copyrighted DVD.
Basically it makes a copy of the DVD without the protection, and is useless if your source is not encrypted
In this way it would no help for converting vob into another format.
There are many conversion tools that can translate your vob files into mpg, avi or any video format you want.
Among the best are MaxDVDtoAvi ,total video converter, Imtoo, Canopus Procoder, or some other that simply merge vob or mpeg files into one.
google on " DVD rip" and you will find thousand of them.

Giroud - I will have to respectfully disagree with this, and perhaps you are thinking of a different tool, because I think some of the facts are not accurate.

DVD decrypter will take your dvd content and parse it into individual files or single mpeg streams, either program streams or elementary streams. it does not require your source to be 'encrypted', as I used it regularly for ripping dvd's I created myself on my dvd recorder, which are certainly not 'encrypted' (thus I had a real time hardware encoder - encode, then rip the dvd to have the mpeg stream, which was nicely encoded by the recorder in real time).

but, it does exactly that - extracts the mpeg from your VOB files, so I'm not sure why you say it doesn't.

in terms of being a 'hacker tool', well a knife can be the tool of a murder or a chef. I'm sure that hackers did use it to illegally rip commercial DVDs, but it has many other purposes. and, for what it's worth, it's not clear to me that it's use is still permitted. it was purchased by macrovision I believe and taken off the market (probably due to macrovision concerns of it breaking their encoding). I don't know whether someone who obtained the software before its rights were purchased by macrovision would still be entitled to its use. but, distrubuting it would be illegal, and certainly breaking copyright laws in any form is illegal.

there are now more tools to deal with vob files than there were a few years ago, probably owing to the DVD based camcorders among other things. I think even nero might be able to deal with vob files.

anyway I hope this helps clarify things.

Sorry for the delay. Carnival season just started down here.

Dave, the resulting .vob files where skipping but once I demuxed them they played just fine. Can I make the results .vob files into .mpg files with decrypter?

If I demux, the video will be m2v.

no worries! I figured you were playing with the files, and I think I've seen the VOBs skip when mpegs won't (since they are not the same).

The only use of decrypter I've had in getting mpegs is from all the files from a whole DVD (either on a disk or on the hard drive), e.g. AUDIO_TS and VIDEO_TS folders with all of the IFO, BUP files, etc. I've never tried (nor am I sure whether it will) be able to convert a single VOB file to an mpeg.

when you do convert, on the stream processing tab, you can select demux or not, but you need to click on the stream in order for the radio button to work.

good luck w/ this!
