until you change the strings_de.xml file mp will "think" it is pan&scan mode although due to the changed core.dll the mode is actually smart stretching.
only a screenshot can really prove it is pan&scan or smart...
I copied the patched core.dll into the MP directory ("C:\Programme\Team MediaPortal\MediaPortal") and replaced the original one.
here some pictures.
1. pic is Streched Mode
2. pic is Smart Mode (real pan&scan)
3. pic is Streched Mode
4. pic is Smart Mode (real pan&scan)
You can see the TV logo ist gone in "smart" mode
