Rainbow Six Vegas DVD Backup

[BarryB]

Use a Dual Layer Disc, holds up to 8.5GB of data, sorted!

You could try and delete some folders/files off the disc to fit on a DVD5 if you know the installer doesn't need them, like Acrobat readers, DirectX if the installer does not automatically run a DirectX setup, demo Videos, foreign language files either off the disc or deleting from inside CAB files. Just depends on how the disc has been created.
