    Hi all,
    I have a video that was professionally produced for me a few years ago. I have all rights to this video and need to make additional copies of it. It was originally produced, edited, and copied on a mac. When I make a disk image using disk utility, it produces a .cdr file which will not work on PC computers when burned (but works on the mac). I have found on other forums that the solution to getting this to work on a PC is to change the file extension to .iso . I did this and it prompted do you want to use .iso or .cdr and I chose .iso and then burned a new disk with this disk image. Again, it works on the mac but not on the PC.

    What am I doing wrong?
    I need this disk to play both on PC and Mac but the only CD burner I have access to is on a mac. Help! :confused:

    Is it from a video or data DVD?
    When mounting that .cdr/.iso file and seeing it in Finder, right click on it and select GET INFO and look what it says under General > Format and report back.

    This is confusing. Exactly what is the deal with the PC? If all you want to do on the PC is to play the burned DVD, then the extension of the disc image file is irrelevant. You want to play the DVD, not the source file format. All that you need to do is to launch Windows Media Player and play the DVD.

    Caveat: There no guarantee that an arbitrary spindle of DVD±R/W media will work in the arbitrary drive. This means that just because the DVD works on the Mac does not mean that it will also work on the PC--and vice versa. You must test your media on your combination(s) of burner and player.

    If the media works on the PC, then you should see it in My Computer. For data, the Mac defaults to an optical disc format that is compatible with Windows. If the .cdr is a disc image file of data, then your PC should have no problem seeing the data files. The only issue would be whether or not the Windows computer has applications installed that can open the data files.

    If I click on Get info for the disk image it does not have a format under general. If I click on the disk image and mount it, it says "Mac OS extended" under format.

    Does this help?

    Mac OS Extended it the file system (format) Mac OS X uses and can't be read natively by Windows or Linux. To do so, they need HFSExplorer or MacDrive.
    When you create the disk image via Disk Utility, just make sure to select another format.
    Or have you tried these steps yet?

    Btw, from what medium do you create the copies?

    Here you see a dialog in which you can change the format.

    The burned disk shows up in My Computer but when you click it just shows as a blank disk. When I open windows media player and then insert the disk it does not appear in the left hand column as an option to play. This is why I thought it had something to do with the file format.

    On a PC the original disk pops up in the left hand column of WMP and begins to play automatically. On the mac the original disk opens up some type of media player with an option to play disk and is also able to play. I would like this same functionality in the copied disk.

    I am currently using DVD-R disks to copy but cannot tell what type of disk the original was as it has a printed label sticker which covers the whole disk. Am I using the correct type of disk? Could this be the problem?

    What format should I pick I think I picked DVD/CD master the first time (using the directions you listed). This produced the results listed above. Other options include "read only", "compressed", and "read/write".

    I'm not sure what you mean by "by what medium". It is a disk that I can't tell what type it is because there is a sticker label over the entire top of the disk. I am copying on to DVD-R disks.

    That is really strange, as I suppose the original DVD (with the sticker) is a video DVD, which you can check via looking at its contents via Finder and telling us, if there is a VIDEO_TS folder or not, or you could also open the GET INFO window or Disk Utility to check its format, it should be readable by Mac OS X and Windows alike.
    But if it is a data DVD, then it might be formatted with Mac OS Extended.
    Therefore please check the source first.

    The original Disk does have a VIDEO_TS file.

    And what does it say in the GET INFO window or in DIsk Utility about the format?

    The VIDEO_TS folder (What is the difference between a file and a folder?) does indicate it is a video DVD, which has a file system (format), which allows it to be played in almost any DVD device, therefore a copy via Disk Utility should work.
    I copied dozens of not copy protected DVDs via the method I linked to (http://www.kenstone.net/fcp_homepage/making_dvd_copies.html) and it seems you are doing the exact same.
    In my experience with this method, the resulting video DVDs should work on a Windows PC or in any DVD player (the ones under a telly).
    Therefore it would be important for you to check the format of the source DVD. Btw, is that source DVD capable of being played back in a Windows PC or a DVD player (the one under the telly)?

    Get info for the disc says "Mac OS Extended" under format. When I open the VIDEO_TS folder on the PC I see that there are both .VOB (that have a WMP icon) and .IFO files in the folder. Could some of these not be copied when copying on the mac?

    The DVD shows Mac OS Extended as format and can still be seen in Windows? What does Windows say when you select the DVD drive i Explorer and press ALT+ENTER?
    Anyway, there should be three file types inside the VIDEO_TS folder:
    • .vob - the actual video
    • .ifo - the menu information
    • .bup - the backup of the .ifo files

    If the video DVD is not copy protected, then Disk Utility should make a working copy, but I am still baffled by the original video DVD using the Mac OS Extended format and still be readable by Windows.
    Hmm.

    It does have all three file types.
    When I select the disk drive and ALT+Enter it says under general type: CD drive, file system: UDF and shows all space as used.

    Hmm.
    UDF is short for Universal Disk Format, therefore being able to play in a lot of devices and a lot of OSs.

    I am not so sure why the original DVD would show up formatted as Mac OS Extended in Mac OS X though. Does it show up as Mac OS Extended in the GET INFO window or in Disk Utility or in both?
    Btw, how much disk space does the VIDEO_TS folder (the AUDIO_TS folder, if existing, is probably empty) use? Is it the same in Windows as in Mac OS X?
    I suspect a session DVD or something similar, where there are two versions of content on the DVD, one for Mac OS X and one for the rest, but if that would be the case, the original creator must have missed something, due to Mac OS X being able to read UDF.

    Anyway, you could try Burn (free) to burn the ripped contents of the original DVD onto another DVD using the Video DVD template.
    Or you could try Burn and use the Copy template and see if it copies the DVD alright.
    The following guide has some hints on how to rip.

    Actually, I can't access the Burn site as I am on a university network and it is blocked. I will keep trying to mess with disk utility and see if I can come up with anything. Thank you for trying to help!

    It's my fault, I gave you the wrong link. Try this one: http://burn-osx.sourceforge.net/Pages/English/home.html

    Not really, as video DVDs include several titles and chapters normally.
    I am just baffled, why this DVD shows up with Mac OS Extended as format in Mac OS X, while it shows up as UDF in Windows, and why you can't use Disk Utility to make a proper copy.

    This may seem dumb but I'm not sure how to use this program. All I see is a disk and a place to rename it, a bunch of blue and while lines a +/- button. I have inserted the disk but there is doesn't appear anywhere. If I click the + and click the disk and click open it says "Some incompatible files. Would you like to convert those files to mpg?" and then asks were I want to save these. Should I save them and where? How do I use them once they are saved.

    Have you tried the COPY tab, either with the original DVD as source and/or the .cdr?
    The white and blue lines are the same ones as in Finder.
