It's true though, there is... I have had this problem with cds burnt at 52X that would only work in certain players (only once, because since then I have burnt a lot slower). I consider 8X to be pretty much safe, and sometimes burn faster (up to 24X for audio). Data seems to be fine whatever speed you burn at. That's just my experience, my advice would be to buy a decent cd player (preferably a standalone stacking system)
