    Im looking for an app that will extract the mpegs from an import DVD.

    I've tried gumby, but it wont wont...I've looked at the disc and its a .dat file, so that may be a sticking point.

    Any help would be great :)

    Wait, do you want to extract the MPEG from a DVD or a VCD? They are two different things. In a VCD it is pretty easy. You can just go into the files and find something with an MPG extension, and drag it to the desktop. With a DVD you can't really just "take out" the video portion. otherwise there wouldn't be a point to having conventional DVD ripping programs, you could just nick the Mpg file and convert it to whatever you want. A DVD is all complex, with menu files and sound files stored separatley, and various bits and pieces stored all around, plus it is encrypted to keep people from bootlegging the DVD. If you want, you can rip the DVD with Handbrake, and simply set the size limit really high to get a really high quality DIVX file. You can get Handbrake here: http://versiontracker.com/dyn/moreinfo/macosx/21117. :)

    if its a dat file all you have to do is change the file extension to .mpg. if its a bin and cue file you will need a app call gnu vcd tools to extract the mpg from the .bin file. hope that helps

    Apparently you can change the .dat to .mpg. It's strange though, I popped a VCD in my computer and came up with this...it plays in my DVD player and that .MOV file plays in quicktime... :confused:

    how do i change a .dat to .mpg ....on the disc itself ?

    Its weird i can even copy the .dat file to my desktop or a folder.


    EDIT :

    So I've toasted the .dat file. I know have a 1.1 gig image file of the first half of my vcd. SO my question is can I do the same thing to the second vcd and some how make 1 dvd from the two image files ( maybe an app of way to JOIN these files ) ? OR is there still and app out there that will either...

    A. Actually COPY the .dat file to my desktop ( NO clue why it wont let me do this.)
    B. Rip the .dat file to an mpeg

    What does it do when you try to copy the file to your desktop?

    There aren't very many VCD apps out there for mac, only a few apps that will play VCDs, so you are kind of on your own.

    ive just had a go at this, copying AVSEQ01.dat to desk top & renaming to AVSEQ01.mpg & it work fine. So it might be that there is problem with the VCD.

    I'm still not 100% sure I understand what you're trying to do, but here's a bit of background info that might at least be helpful (and by the way, 10.2 and earlier can't read VCDs; 10.3 can):

    The .dat files on VCDs are indeed the video, and they do contain an MPEG1 stream of data, but they are NOT just .mpg files. They are an .mpg file with some extra data in there (I believe for error correction), and although Quicktime can play .dat files without changes, it seems to prefer .mpg files and if you're working with them, real .mpg files are accepted by more programs.

    If you want to just play a VCD, and are using 10.3, just open the .dat file off the disc from QT player, or tell QT Player that it all .dat files belong to it--then you can just double-click one to play it. Works great.

    To convert a .dat to a .mpg, the easiest thing is to process it with an app called VCDGear; nobody doing anything do VCDs should be without it. You can also ask it to fix broken spots in the file while it's at it, which are surprisingly common--I've seen many VCDs that stick in QT Player but work fine after VCDGear cleans them up.

    To copy a .dat to your hard drive, you again need 10.3, but can just drag the file using the finder. 10.2 and earlier couldn't properly read VCDs, which is is think the error you're getting--it just plain wouldn't work (I was so happy to see this fixed in 10.3--worth the price of admission right there). There was a shareware app that could read VCDs under 10.2, but I can't remember what it was called. Anybody?

    As for combining .mpgs from two VCDs onto a DVD (at least, one that can play on a TV), I'm not sure; Toast should be able to do something like that, or if you can get the two to import into iMovie you can use iDVD to burn a disc, but that's all I can think of.

    .bin and .cue files I believe are only for people making "images" of VCDs; I don't think you'll find those on actual VCD discs.

    Whew. I don't know mate. I don't really know what you should do, if you can't copy over the file. Maybe try some sort of backup program? See if it will copy the file for you. There are a bunch on http://www.versiontracker.com.

    ok...

    so heres what im thinking....

    I made an iso/toast file of disc one of the VCD, Im going to do the same thing to disc 2. SO I'll end up with 2 ISO/toast files that make up the vcd.

    Can i then somehow extract or re-encode those into a file that can then be joined and or burned with toast so as to make a DVD from the two ISO files ?

    Can I mount each iso and then convert it to something ?

    Well i did.

    since there was no app to extract the .dat file from the VCD...and the discs wont let me copy the files from the vcd to my comp I did the following.

    - drag the .dat file into toast
    - save as a disc image
    - repeat steps for disc 2
    - mount each iso
    - open the "dvd"
    - copy the VOB files into a new folder
    - toast new folder with 2 VOB files ( one from each VCD disc )
    - take out new DVD and watch two men in monster suits fight !

    I feel so geeky, but damn i like problem solving on a mac !

    Sounds like you got your problem worked out, which is good, but I'm pretty sure like I said before the reason you can't just copy the .dat file is because you're using 10.2 (or earlier).

    VCDs use a special format, and versions of the MacOS earlier than 10.3 do NOT know how to read that format. Toast does, so you can get data using it (what you ended up doing), and MacOS 10.3 does, so you can just copy stuff with the finder using it.
