Not everything plays "nice" with Vista, with it being so new. I imagine the only program that plays well with it is Microsoft's own Windows Media Player 11 for Vista. You could try iTunes, but Apple has cautioned iTunes users not to upgrade to Vista just yet. But I know of a few people who have used iTunes on their Vista machines and they work just fine.
ever since i have gotten my new labtop with vistas, i cant get a mp3 downloadable program to work. i want to burn music etc, what ones will work that will not freeze up?
