My skin is based and is a derived work of the default PLi-HD skin.
if the default Pli-HD skin works fine, mine should work fine also unless you have an old version of the PLi-HD skin...
In your screnshot, I can see that for the same channel and the same program (BEARS) at 3 minutes of interval, my skin shows it as HD and the default PLi-HD shows it as 4:3.
Then it make me think that your image/skin is definitely not up to date.
Plus, I don't know OpenRSI,
Sorry
