No, it's not. But there are a lot of variables no one even considers. You could have a crap burner with no writing strategies for the good media, but does have one for the poor media and the poor media will come out better. This doesnt mean the poor media works better than the good media, it just means your writer isn't the one for burning the good discs. This is quite a complicated topic and it always gets over simplified to "burn as sloe as possible", which is also wrong.
On the Taiyo Yuden front, these might be cheaper for you depending on how much a proxy bidding service would charge: http://page12.auctions.yahoo.co.jp/jp/auction/p517359671
As mentioned above many other variables come into the equasion such as computer hardware, condition of laser in game console... etc. some brands what happens with time and change of humidity , oxygen the dye will wear out to be such as translucent holes in the underside of the disc, common with third party discounted brands.
Yes it does, I had found a spindle of vintage black memorex cd-r's at a garage sale and guess they were over 20 years old, tried to burn a playstation game and when it was tried it would constantly freeze and glitch in the gameplay. What I would like to know is what the difference is in the colors of cd-r's mean ? theres like atleast 10 different underside colorings ranging from silver,black,blue,green, rainbow etc. Is there some reason for this, like say how old vinyl records play music slightly differently than cd audio ?
digital is digital, it won't sound better but it does determine how hard your laser will work reading said disc.
