MediaPortal is a .net based Windows Media Center alternative, which supports music, video pictures and TV and they have just released an updated version of the system. MediaPortal 2.2.2 has improvements to TV and Radio plus a couple of bug fixes:
One-click deletion of grouped recordings: Grouped recordings in the TV recording folder, e.g. series, can now be deleted with one single click instead having to go manually through each individual entry.
Radio recordings: You can now skip, pause and resume within a radio recording like in any TV recording
Manual schedules: Manually added schedules will now appear in the list of scheduled recordings
Client wake-up at 2:00: A bug that caused a client to wake up every night was fixed.
Party Music Player: The party player is now capable of handling large playlists with more than 1000 entries
