I'm using the latest version of smplayer, with the keys "W" to zoom out (Zoom-) and "E" to zoom in (Zoom+).

Anything after r33488 exhibits the 'zoom' problem mentioned, and other than exchanging the mplayer versions I made no other setting changes.  Running with Win32-sp1.

Doesn't seem to fix it. What happens is in fullscreen it can't zoom over 
the screen size in fullscreen. It used to be able to but more recent 
versions (occurring after r33488) aren't able to even with 
directx:noaccel; direct3d/gl work.

I can't test from the command-line, the 'panscan' command isn't doing 
anything.
