Rayman 2 and Rayman M

[reasonuser]

Hi!

I'm new in this forum and I have a question regarding Rayman 2 and Rayman M. I want to make a DVD containing all Rayman Games to install them on Windows 7 64 Bit but I have problems with Rayman 2 and Rayman M.

Rayman 2:
The CD is about 650 MB big but if I want to copy it to my harddrive, it is about 6,5 GB. It's the files in the folder Data/Levels which become that big. How is that possible and how can I fix it?

Rayman M:
I copied the content of the 2 CDs to my harddrive and made an iso-image. But the installer keeps asking for the second CD no matter what I try. There is no msi-file I could edit nor is anything written in the autorun.ini.
If the iso is called like the second CD the installer asks to insert CD 1. So it seems to depend on the name of the disc. How can I change that?
The other games work fine.

I hope you can help me with this!
