[libavg-users] SDL weirdness OS X

[Justin Maynard]

System (OS X 10.5.6, libavg 0.8.0, 15" Macbook Pro, ATI Radeon X1600,
24" Display 1920x1200)

I've got a weird SDL bug. If I try 
Player.setResolution(1,1920,1200,24)
I get 
ERROR: Setting SDL video mode failed: No video mode large enough for
1920x1536. (width=1920, height=1536, bpp=24, multisamplesamples=1).
and if I try 
Player.setResolution(1,1600,1200,24)
I get 
ERROR: Setting SDL video mode failed: No video mode large enough for
1600x1280. (width=1600, height=1280, bpp=24, multisamplesamples=1).

It's like its ignoring the height and forcing a 5:4 aspect ratio.  I
tested this theory with.
Player.setResolution(1,1500,1200,24)
and it worked.

I'm assuming it's something in OS X or an interaction with the monitor
(Dell 24" via DVI). I've got another machine running an interactive with
three 1600x1200 displays under ubuntu doing a 4800x1200 display with
libavg so I'm guessing its not libavg.

Any ideas?
