Ok, I had a problem with pixelation near the end of the movie. I'm now only using good media, no longer using labels and limit my burn speed to 4X like most of you reccomend. My question is this: Is it better to burn at 4X with 4X media or is 8X better ? I use Ritek printable media and it's only a few cents difference between 4X and 8X. Burning at 4X is one better than the other ?
