Please which is the best choice for a DVD Burner? It must be internal and compatible with an ATAPI interface. I have a Power Mac G5.[/QUOTE]
If you have a Mac, then I would go with a Pioneer DVR-115D (or DVR-116D if the 115 isn’t available). Macintosh computers have a long and close history with Pioneer DVD drives, so they are the best and easiest choice if looking for a replacement.
Keep in mind that a Mac will work with any DVD drive, so you don’t have to choose a Pioneer, it’s just that Pioneer drives have been installed from the factory with Macs for so long, that there is a huge base of knowledge and a large community of people to answer almost any question you have regarding using a Pioneer drive on a Mac.
