Hi Michiel,

With that that increase in speed also came an increase in content. So better compression still made sense...

That's true...

A few years back I wanted to read some stored CD's serveral years old, and I couldn't. In hindsight, it wasn't that surprising. They were stored in the living room in a rack, where light could get through to them. And they weren't the best quality, certainly not archive quality...
Bye, Wilfred.
