Microsoft have certainly made the compatibility mode powerful in Windows 7! I could only get basic use from my Zen Xtra in Vista, using Real Media Player to play tracks from the Zen Xtra, but in Windows 7 it works flawlessly. Basically the driver for the Zen Xtra is incompatible with Windows 7. However, if you download the XP driver and right click the installation file and select the Troubleshoot Compatibility heading and use the recommended settings to install the driver, then install the Creative Mediascource 5 for Vista, then the plugin for the Zen Xtra for Mediascource (both install without compatibility mode), you will get a warning that the driver is incompatible but ignore this and restart the computer. I then started Mediascource software, noticed the Zen Xtra listed, clicked on 'Playlist', and it loaded, no problem! Playback, no problems, transfer to player, no problems! I am NOT using the 'Play 4 Sure' firmware update either! Also for those with the Audigy 2 or 4 sound cards, Creative have issued a beta driver for Windows 7, I am using this without the previous distortion that the default Windows driver gives. Everything is cool! This was my main reason for not replacing XP as my main OS.
