Hi Matt. I do see these in the log (below) and all seem to have a return code of 0. However, I think I've worked out what might be happening!!!
The arrow keys are working. What's occuring though is that the on-screen DVD menu cursor is hidden! The enter key also works - taking me to whatever menu selection I've blindly navigated to.
I have a couple of PC's in the house both with MC loaded and both behave in a similar way with DVDs exhibiting this problem. Of the DVDs I own which work fine, I still noticed that some menus (when first loaded) also have no sign of the cursor anywhere on the screen but as soon as I arrow down or across, the cursor appears and I can see what I'm doing. For some reason, the cursor never re-appears when doing the same thing with certain other disks (or more precisely, their menus).
Perhaps MC is doing something behind the scenes which is inadvertently hiding the on-screen DVD menu cursor in some cases.
Hope this helps,
