I have some new results below that may preclude this.
(But I will if I must :-)

The problem appears to lie with my strange video card.
Recall that the card is a special one provided by ATI to
Tohsiba to drive their 4096x2160.  My understanding from Toshiba
is that it merely had its timing circuits tweeked to handle the
special reqs. of their 4096x2160 display.  But evidently the
card is very limited.  For example it does not seem to 
"XV" capability.

In the current case I'm using the card it to drive an ordinary
1920x1080 Flat Panel.

The avi plays just fine using the .i386 (32-bit) version of the same
mplayer package under both Fedora Core 5 and Fedora Core 6.  Indeed,
I've been contructing such raw RGB avi files from individual image
sequences (using transcode) for four years and mplayer always happily
plays them.

I don't know what this means.

Here is what I discovered last evening.  It it related to your remark.
The ATI card has some very odd limitations.  When I tried
this commandline:

  mplayer -vo x11 -vc rawbgr24 sequence_1.avi

the sequence plays except its flipped top-to-bottom.

I think  .avi was encoded by transcode as "rawbgr24flip".
(Not sure what I'm talking about here :-)

Here's what midentify give (on a machine where mplayer works properly):

    ID_VIDEO_ID=0
    ID_CLIP_INFO_NAME0=Software
    ID_CLIP_INFO_VALUE0=transcode-1.0.2
    ID_CLIP_INFO_N=1
    ID_FILENAME=sequence_1.avi
    ID_DEMUXER=avi
    ID_VIDEO_FORMAT=0x00000000
    ID_VIDEO_BITRATE=331776000
    ID_VIDEO_WIDTH=1280
    ID_VIDEO_HEIGHT=720
    ID_VIDEO_FPS=15.000
    ID_VIDEO_ASPECT=0.0000
    ID_LENGTH=36.67
    ID_VIDEO_CODEC=rawbgr24flip


If I use either

mplayer -vo x11 -vc rawbgr24flip sequence_1.avi

or 

mplayer -vo x11 -vc rawbgr24 -flip sequence_1.avi

mplayer crashes. Just before it crashes it puts up
its display window for a split second.

Is it possible that the card is unable to "flip"
and mplayer crashes when it tells the card to do so?
(I dislike this ATI card, but I'm unfortunately forced
to use it to do my work :-)
