I bought this heavily-discounted Xdock as a video interface - to allow me to view TV shows purchased on iTunes on my flat screen TV. Also driving this decision was the compatibility mess that Apple has created, with regard to which video output cables will work with which generation of iPod (and this extends to the version of firmware the iPod is running)... And, the price of the typical Apple composite output cable was more than the entire Xdock! Seem like a win-win situation? Sadly, it turns out that Xdock too has a limited compatibility list for video output, so if you have say an iPod Nano (g3 or g4) you are out of luck. On the upside the unit is well-built, with a nice remote. It can connect via Toslink, if you have a spare optical input on your amp/receiver. The sound enhancement features are switchable, do work, and the effect is noticeable though not overpowering, especially for lower-bitrate MP3's. So, if you are looking for an inexpensive way to connect a dockable iPod to your home theater controller for music, this unit could be what you need (although there are many, many other choices). If you want to show video, make very certain that your exact iPod is supported before you purchase the Xdock.
