Copying VCDs with menu from HD backup

[Ramautet]

Some time I back up VCDs on DVD-R, and when I want to burn them for someone, I just copy them on the HD and then select the DAT files in Nero with the VCD option. I cannot make direct VCD copies anymore, since VCDs are some time much over the 700Mb allowed. Many times they are about 750-800Mb. When you import a DAT file into a VCD layout, it will somehow fit into the VCD (I dont know how's that, but is so); however, if I make a direct copy the DAT file wont fit anymore, since it will keep the original number of Mb.
The only way is to import it into the VCD layout of Nero. And that's when the menu problem show up:
When the VCD has a menu, I'm not able to import the menu. I tried copying the file into the VCD layout of NERO, but the program wont allow me to overwrite the system files the NERO is creating. That is, I can copy manually the file with the menu, but it's completely useless since I cannot overwrite the other files. Anybody knows how to solve this?
Thanks a bunch

Well... just bumping the post up.
Still have problems about how to import the ITEM0001.DAT file into the VCD.

The best way to copy a S/VCD is to do a DAO copy. For example, using something like CDRWin or CloneCD.

Backing up the "DAT" files doesn't make sense. You might as well just back up the original MPEG file then.

If you want to back up the entire VCD structure on something more robust then simply burning a second VCD, then you can't just go around copying the files. You will need to save the IMAGE of the S/VCD.

Most capable CD burning programs now will allow you to create a disc image of your S/VCD, or any CD really. With Nero, have it extract an NRG image, with CloneCD, CCD (I think) image or with CDRWin, a CUE/BIN image.

You can then burn the images as a file/s on a DVD-R or copy it onto whatever backup medium you would like. Then, to create a new copy of the S/VCD, just copy the image files back over onto your HDD and burn the image using the appropriate CD burning proggy.

As to why you can seem to put more data onto a S/VCD than a standard CD-ROM the answer is here: https://www.videohelp.com/forum/userguides/135642.php
