I can confirm this bug also, using an ATI X1300 mobility on ubuntu 6.10 and
8.33.6 driver.

Also, some more to add:
Normally, using mplayer with xv video output is fine, as is the
$gst-launch-0.10 videotestsrc ! xvimagesink    videotestsrc ! ximagesink
pipeline (with a small exception of one of the bottom colours being slightly
more purple on the xvimagesink than on the ximagesink).

If, however, I run totem, then until a reboot mplayer shows the funny colours.
Using gl2 output solves the problem from a user perspective. This also causes
the pipeline above to produce funny colours.

I have been doing some hacking on pipelines with an xvimagesink, and I can say
that the following pipeline seems to give the same problem (from cold - ie
before totem has caused the problem):
$gst-launch-0.10 -v filesrc location=photo.jpg ! jpegdec ! freeze !
ffmpegcolorspace ! xvimagesink

I will confirm this behaviour when I have a moment, and whether it results in
the same system wide changes.

So, in conclusion, xv seems to be fine on the system until gstreamer triggers
something, when all programs that use xv start exhibiting the bug.
