    Hi, I am newbie at this and I only have a cd-r, no dvd at all. I made a vcd using Nero and I lost all the original mpgs. All I have now is the DAT files on the vcd. I would like to make an edited copy of this vcd - specifically, I would like to remove one dat(mpg) file and replace it with a different one. I thought this would work:
    1. Copy all the vcd files to a folder on my hard drive.
    2. Delete the dat file I don't want and replace it with another.
    3. Then burn it all as a DATA cd.
    But it ended up too big too fit.
    (I guess vcd uses less space than data?)
    I just started getting into this about a week ago so any tips and help will be much appreciated.

    Use VCDgear for the DAT<->MPG conversions. Also, VCDs are not DATA CDs, so you'll have to re-make the VCD from the MPGs (easy enough).

    Thank you for the help. Just one thing, I do know that vcd is not the same as data cd, but what I don't know is this: Imagine copying all the folders and files from a VCD to your hard drive and then burning them all to a new cd as a data cd. Both cds would then contain exactly the same content. Would these 2 cds then be and work the same?
    thanks again - this is a great forum. I have learned a lot already.

    Actually I have tried that before back when I was completely new to vcd but it doesn't work. Not even on your computer using WinDVD it doesn't work! Maybe on some stand-alones it does but not to my knowledge!

    to answer your question, when burning a VCD it does take up less space because it does not use error correction, which in turn makes it so that you can fit more data onto one disc. If you use Data CD compilation, it automatically changes the format and forces CRC, which negates the effects of burning a VCD. If you are going to use a different MPG file, just create a new VCD compilation with the new MPG, and forget about doing it the other way.

    my 2 cents.
