I've just finished a quick-and-dirty MediaPortal plugin to add a Digitally Imported radio option to the main menu. At the moment it seems to be working for me, but I'm looking for other people to test it so that I can improve it.
The plugin loads the main page and playlist pages from the Digitally Imported website and displays them in a hopefully-friendly format. It's not internationalised at all yet, but if people are interested in writing non-English translations for the strings in the plugin I'd be happy to add support for that.
The plugin can be downloaded from
http://www.keogh.net.au/mediaportal/diplugin2.zip - just put the diplugin.dll in your mediaportal\plugins\windows directory, and put the diplugin.xml into your current skin directory (mediaportal\skin\BlueTwo if you're using the BlueTwo skin). There's a screenshot available at

Please download it, give it a try, and let me know what you think. This is my first MP plugin, but hopefully it's usable.
