If the game is using the installshield system with it's .cab system, then any game spanned into various CD can be easyly passed into one DVD. You only need to maintain the folder structure and put every datax.cab together. Installshield uses a very simply routine to determine where it place it's .cab and it only ask for next disk ( in the proper CD if spanned) if no files are found. Putting all the .cab together should solve that problem and no replacing/next disc dialog box should appear. In the other way you can be handling a not common installshield engine based, for example the new windows installer system. This way differs a lot from the other using "common" .cab with digital sign in it making it harder to crack.

First you should also know what type of installation do you have cause i'm not sure you where talking about a Installshield one.

TIP: Maybe you have "cracked" .cab files and files into the CDs which no correspond with the header in size nor CRC check with original placed into the .hdr file if present. This could give you that problem. ( Usually gives a CRC error dialog box)

And something more, that forgot lines above. If you have in different CD the same file with different sizes, you must preserve the largest one. If there is multiple files in different folders, you must preserve the folder estructure or will have a pretty bug between hands^^
