I am releasing a beta version of my MediaPortal plugin for everyone to try out. This will only work for the Windows PMS but it should work in just about every client. Please check the readme for some quick installation instructions. If anyone has any questions please let me know.

If you are running into any issues please post your mediaportal and system log files so that I can help debug the issue. Thank you!
