When I added the pixel format stuff, best as I could figure, only one of
the two byte swapped packed 24bpp pixel formats was attainable with the
Bt848 (works on S3 chipsets like my Virge/VX). You can see the supported
driver RGB pixel formats using fxtv -debug startup:
Supported RGB Capture Pixel Formats:
bpp Bpp RGB Masks Swap
--- --- ---------------------------- ----
15 2 00007c00, 000003e0, 0000001f NB
16 2 0000f800, 000007e0, 0000001f NB
24 3 00ff0000, 0000ff00, 000000ff B <-----------
24 4 00ff0000, 0000ff00, 000000ff NBWb
Which frame buffer format can't be queried in XFree 3.3.1 and prior
versions (I've been told that it might be in a future version though) so
Fxtv tries to guess the Bpp from the Display pixel formats or visual depth,
and it makes the user specify the pixel format swaps via resources:
Try these two commands:
fxtv -xrm "Fxtv.bswap3Bpp: true"
fxtv -xrm "Fxtv.bswap3Bpp: false"
one of them will give you DirectVideo. If the colors look good, great --
keep it. If the colors are "psychedelic", the frame buffer format of your
card is the unsupported Bt848 24bpp swap format. Note: it may be that the
Millenium supports both 24bpp frame buffer orders, but that your X server
just configuring up the one the Bt848 doesn't happen to support.

Hmmm... Maybe diff server? Possibly 32bpp frame buffer format in reality?
Don't know without more info.
