Nice overscan skin

[Shader]

Does anyone know a good overscan-corrected-skin?

I am using overscanned (tv-mode) output on my Radeon and BlueMCE2 as skin
but all the edges are 'cut-off'.

It's easy to make your own.
Open the background.jpg in any editor.
Shrink the picture by about 20 pixels on all sides.
Resize the canvas to the original size (720x480), and save it.
The border size will depend on your TV, and how much overscan it has...every TV is different, so for me to create a background, then send it to you, may be totally pointless
Most skins (and gbpvr by default) has most things contained within an overscan "safe" area anyhow...so providing skin designers are aware of this, you should have no problem with any skin.

It's not the background that's the problem, but the buttons on the left side of the screen when using the wheather plugin for example.

Get the skin/plugin developer to adjust the button placement.
These should be adjustable in the skin.ini, but not always are.

Just start it in window mode and use the -pos:x,y,w,h command line argument to line it up perfectly with your TV.
