Video playback on wide monitor ?bug?

[hschulze]

When I play back a video like 720x480 on a 2560x1600 Dell 3007 panel, the rightmost area, possibly the part past 2048 pixels out of 2560 is black. As a window or full screen. As soon as the window increases past 2048, it seems to get smaller in width. In other words, a full width window that's just a few pixels high has a tiny video area - then as I increase the height of the window, the video gets wider and higher (expected) - until it reaches 2K wide, then it starts to shrink.
I checked the same video on iTunes, and it plays fully full screen, windowed or full screen.
Is VLC doing some sort of 11-bit math here and wrapping?
The left side of the video always completely reaches the left side of the monitor.
Video card=NV41 Quadro FX 3450/4000, driver=186.18
OS=XP32 SP3 on Intel E7300 Core2Duo.
Not sure about other platforms, so I posted under Windows.
This happens under DEFAULT video output, but not under OpenGL nor DirectX.
The Video options are Accelerated=checked, Decorations=checked, use HW YUV->RGB conversions=Checked.
I tried a Reset Preferences, still repros. Now on GoldenEye, I noticed this issue first a while back, maybe around 0.99 or so.

Default video output module is DirectX under Windows XP.

Default video output module is DirectX under Windows XP.

Then WMP uses something other than DirectX? WMP works.

WMP uses VMR output which uses either Direct3D or DirectX. But the display code ain't same.
