Jesus, the burning speed argument AGAIN?
It all comes down to several variables: your burner, pc, media, and Wii. In my case, using TDK -R media, burning at 8x is FAR more reliable than burning at 2 or 4x. Generally speaking, burning at 1/2 your drive/media's maximum speed is optimal. 16x? Burn at 8. Keep in mind also that some people have very old computers that simply won't even keep up when burning at high speed... this can cause errors as well.
But all in all, there is NO definitive answer to this question. Use the media and burning speed that give you the best results. I burned MPT twice, on Imation DL discs. The faster burn of the two is definitely more reliable (100%) than the slower. This applies to the copies burned on my brother's machine as well. But obviously BladeXDSL has different results. And if you look in about 5,000 different places on this board, different users have very different results based on high/low speed burns.
Why does everybody around here have to assume that there's only ONE right answer to this question, and since it works for them, anyone doing something differently must be completely wrong?
