I have done some XNA work on the zune in my past, but I started a new project which is my first ever to use the zune in landscape (wide) mode. In XNA / C# there's no official way to make the zune draw that way as just a switch. So I searched
zB and the web for examples and ideas, and originally I only got lost. I eventually found a thread in the official XNA site, and it looks far clearer than any other information anywhere else I found. So, after all that, I've decided to share what I found.
Here's the link:
Zune In Landscape Mode? - XNA Community Forums
enjoy!
