There won't really be any result. PS2 lasers might be bad, but not that bad. I've heard of the new V9/10 lasers burning themselves up in a matter of months and that, but if you use good quality +R media, you'll be fine. Using crappy +R media, will only have the same effect as using bad -R media, so use good quality + or -R media and you won't have a problem. No real damage will come of it, it's just that the PS2 has better success with -R. Hope this helps... LUFCfan
