Hi utu
Yes indeed, if you run testcd on the Linux Magazine (EN) dvd you get the reply

checking KNOPPIX/KNOPPIX...Failed!

whereas if you run it on the LinuxUser (LU) dvd you get instead

checking KNOPPIX/background.png...Fehlen!

I'm not a great German scholar but I think I can make a good guess at what 'Fehlen!' means.

In each case after the Failed/Fehlen message it asks if you want to continue anyway - but that is to continue with booting from the dvd rather than to continue with testing the other files.

The difference is that for the LinuxUser dvd according to the sha1sum test done individually on each of the KNOPPIX/* files <background.png> is the only one that fails and I think I can live with a different wallpaper image.

In the Knoppix Magazine dvd the <KNOPPIX/KNOPPIX> file is the only one where the computed sha1sum differs from the value given in the file <sha1sums.txt> and that is something that at least potentially could give problems with using Knoppix 7.0. Whether it actually does cause problems I haven't found out yet.

I have so far found no problem with using the Linux Magazine (EN) dvd, either directly or as a hard drive install but then i probably use regularly less than 10 out of the 100's of programmes available on the dvd. But I am definitely going to use the LinuxUser (LU) dvd and hd install from now on at least until someone who knows a lot more about it explains why that isn't a good idea.

Hope this helps.

Best wishes, John
