I personally think that that's always a bad move, unless you know that the disc is "pressed", not burned. And with the exception of the mass runs done for trade shows like TAG, most Knoppix discs are burned.

Those who sell this free software generally do it to make a profit. That's perfectly legal. But since they are driven by a profit motive, they generally do high speed burns. You don't really expect that someone selling you that £1.70 disc is taking more than 20 minutes to burn it and doing so on quality media, do you? The disc may suffer the same problem or not even boot at all on all systems, and from what we already know your system may already have optics that don't do well with a less than perfect slow speed burn. You apparently already know how ot burn the disc, since you seem to have made your first one. You didn't say what speed it was burnt at. But I really expect that if it was made at high speed then you could resolve all of your problems just by making another disc at 4x speed.
