|It doesn't seem to work for me. The behavior is still the same as before.
|I have to have something partially blocking the fxtv window in order for
|the video to update.

|I'm using XFree86 4.1.0, with a MGA driver I built back in March from the
|XFree86 CVS tree.
Hmm. I received mail from Frank Nobis last night who has a G450 running
XFree86 4.1.0 on 4.3-S SMP with DGA & no problems. Here I've got
G450/4.0.3/4.3-S. So the "MGA driver" version difference may be the
difference between your two configs. Also appears XFree86 may have fixed
the GetVideo bug/feature in 4.1.0.
I really just got my G450/Athlon system built and haven't yet gotten to
tuned it up for FreeBSD/XFree86 (DRI, mga/agp modules, etc.; any URLs to
web pages or list posts appreciated). So I'm not sure exactly what you
mean when you say "MGA driver". Is this the MGA kernel module? The driver
linked into the "XFree86" X server?
To your problem, here are a few DGA tests:
http://people.freebsd.org/~rhh/fxtv/dgatest.c
http://people.freebsd.org/~rhh/fxtv/dgafbtest.c
http://people.freebsd.org/~rhh/fxtv/tv-dgatest.c
It would be interesting to see if these work for you, and what the first
one prints. The first dumps the GetVideo returns. The second draws
crosshairs in the corners of your screen via DGA & /dev/mem. The third
plops a frame of colorbar video in the corners of your screen, and then
bounces a TV around (to test TV card memory access vs. CPU memory access).
