Sony Bravia TV's (like my KDL-46EX725) only support JPEG images with YCbCr 4:2:2 or 4:2:0 chroma subsampling. JPEG YCbCr 4:4:4 is not supported If you edit pictures with Photoshop or PaintShop and save them with 4:4:4 chroma subsampling (which is the default in most cases) the pictures will not render on the Bravia TV's.

Attached is a hack which solves the issue by transcoding the images. Additionally the images are resized to the screen resolution (the resizing of the Bravia sucks!)
