Hello,

the first time I noticed a problem with the DVD was when I tried to use the feature of copying it to HD from the running Live system. It always failed towards the end of the process. And GRUB is not being updated. When I update GRUB from a different linux installation it finds KNOPPIX and puts an entry into the boot menu. I can start it from there.
Then I ran knoppix testcd and it fails. I tried testdvd and it fails too. Then I thought I have a broken copy so I wrote to Linux Magazine and they sent me a new copy. But it has exactly the same problem.
My machine has 4 GB of RAM of which I have set 1 GB for the video card. My CPU is AMD E350, which is an APU (CPU+GPU).
I tried this on a laptop with 6 GB of RAM and it has the same problem.
I am wondering whether I need more RAM in order to get a successful testcd/testdvd?

Best regards,
Stefan
