I have two different versions in my collection (and I'm always looking for the original POLAR CD !!!).
The first one was released on german POLYDOR label (831 596-2). Year unknown. The CD includes 5 bonustracks, taken from the albums "Ring Ring" and "Waterloo". The front cover shows a different logo than the regular vinyl versions (see picture).
The second one is the SOUND & VISION CD/DVD edition, released by POLAR in 2004 (0602498107287).
The frontcover has a different logo (the real logo with the reversed "B").
The CD includes the following bonustracks:

- Crazy World
- Medley

The DVD contains the following videos:

- Mamma Mia
- S.O.S.
- I Do, I Do, I Do, I Do, I Do
