Hi Louis.  Sorry it took so long to reply, but I've been away on business
last couple days.

There isn't any image capture implemented in fxtv yet.  But if you mean the
snapshot button (camera icon) that freezes the video, it should work OK --
given that the X server returns the correct pixel geometry in the TrueColor
visual info.  That is, if the frame buffer is 24 bits per pixel with 4
bytes per pixel, the pixel depth is "32 planes" with R,G,B masks that just
use 3 of the 4 bytes.  E.g. from my card:

       visual:
         depth:    32 planes
         red, green, blue masks:    0xff0000, 0xff00, 0xff

The video and freeze frame both work OK.

I'm guessing your X server visual info doesn't reflect the actual pixel
geometry.  Are you running with an XF86Config Depth line of 24 or 32?  If
24 and if you know that the frame buffer mapping is really 4 bytes per
pixel, this is probably the case.  Do an xdpyinfo and look at the TrueColor
visual to verify.  Also, I'd be interested in a copy of the output.  I'd
like to help get you up-and-running if I can.
