First off, movies downloaded from Limewire, YouTube, etc. are often highly compressed to begin with. There won't be much you can do with video files like that because they've already lost a great deal of their original resolution and color information. This is true of ANY platform, not just a Mac... At best, you can do rudimentary color correction like contrast and saturation, but making the image sharper is out of the question. You'll run into similar issues with sound. Compressed sound is not easy to work with.

As for your second question, blank DVD media does vary in quality and different DVD-RW drives have issues with certain types of media. I exclusively use Verbatim media for everything; I haven't found a single functioning drive they won't work with. I generally use DVD-R (as opposed to DVD+R) because it tends to be compatible with a wider range of set-top DVD players.

Hope that helps you out. ;)
