MediaPortal has a new update to their Free, Open Source, Windows Media Center Software. This latest version is 1.00.0 RC3 and includes several bug fixes as well as a nice, new default theme called Blue3.
Blue3 uses a cartoonesque “mascot” that fits in well to the media center user interface.
The Blue3 theme isn’t yet available in 16:9, but will be soon. The new theme is very nice looking as are many of the MediaPortal themes. I have a short walk-through of the MediaPortal Interface using this new theme for you here:
Here's a screen-shot of the horizontal menu view which I didn't include in the screencast above:
If you’re looking for a free, open source Media Center software, MediaPortal is a good one that you should check out. My experience with it was that the non-TV media stuff is pretty nice, but the TV engine needs more work. Still, its free and has a large number of followers so its worth a look. Out of the box, Media Portal supports Windows XP, XPMCE and Vista (with UAC turned off).
