I use MediaStream, but I had to heavily modify it suit my needs.
The fonts are tiny, having 3 sections for videos (Videos, Movies, TV Shows) on the main screen is a waste, and having scripts and the file explorer hidden away in the system setting sub-menu drove me insane, as well as fixing the shortcuts for the Programs sub-menu. The skin also lacks a game save viewer, so I have to switch to PM3 to edit game saves.
Now your probably asking why do I use it. lol
I like the layout better than PM3, and that's about it.
It took a bit to get used to, but with all the functionality problems fixed and an hour of cruising the menus, it's very nice skin.
