For a reason I don't understand, using PIL enabled, no picon are displayed on AOTV 7.4b.
The only thing I can think of is that this image uses the latest version of PIL and in this version "Image.ANTIALIAS" is deprecated... but it should be visible in the plugin's DEBUG log. I'll install this latest version of OpenATV tomorrow and check what's up with the PIL library
Currently oatv 7.4 is only in beta version and is outdated for a lot of packages. A lot of commits have to be made in oe-a 5.4 and oatv master repositories.
