I fully agree about the need for more testing.  If I was you I'd be
feeling pretty frustrated right now. Although I think Canonical could do
more testing of Ubuntu before release, I would also like to say that
testing is something that us users can help out with.  Canonical do not
have the money or staffing resources to purchase and test all the
hardware out there.   In this regard, it is disappointing that when you
reported this bug immediately after the release of 11.04 (and therefore
during the pre-alpha testing phase of 11.10), no one responded in a
timely manner.

My observations over the last couple of years have been that even when
issues are noticed promptly, it often takes a whole release cycle to
correct them, due to may bugs being largely out of Ubuntu's hands as
they are in upstream components.  In this case the bug seems to be
upstream in GStreamer and how it works under the VESA framebuffer +
classic softpipe environment.  The GStreamer developers are the ones
with the most expertise in this area.  However it is worth noting that
some people, including Greg Kroah-Hartman from Novell/SUSE's kernel team
have criticised Canonical/Ubuntu for constantly taking from upstream and
giving very little back in the way of patches.

Sometimes it is necessary for various upstream projects, and even Ubuntu
itself, to drop support for older hardware and/or software tools to be
able to fix other bugs, and more importantly, to enable new features.
The reasons described at the first link in comment #10 of this bug are a
good example of that.

If this bug can be fixed at all for future releases of Ubuntu, we will
have to get the upstream GStreamer developers to do it.  I'm not sure
whether much can be done given there is no  DRI driver for the [SiS]
661/741/760 PCI/AGP chipset (see comment #10), but I'll talk to them.
Before I do that, can you try playing the file directly by entering the
following command in a terminal:

gst-launch-0.10 playbin2 uri=file:///$HOME/<path to file>

For example, I have a file called Insalata_Caprese_Rec_317_263427.mp4 in
Ubuntu's default "Videos" directory, so I use:

gst-launch-0.10 playbin2
uri=file:///$HOME/Videos/Insalata_Caprese_Rec_317_263427.mp4

Please report what you see in the video, if anything, and what is
printed in the terminal.

Also, please navigate to /var/log by issuing:

cd .. <ENTER>
cd .. <ENTER>
cd /var/log

and then get the relevant part from the dmesg file by issuing:

cat dmesg |grep drm

and attach the output to this bug report.

Title:
  ABC iView Flashplayer file blacking out on playback

Status in “gstreamer0.10” package in Ubuntu:
  New

Bug description:
  Just downloaded the file spooks_11_09_04.flv (a 640 x 360, H.264 video
  codec / MPEG-4 AAC audio codec, 25 frames a second FLV file) using the
  Python iView file streaming application and, with no other
  applications running, tried to play it back with the new Media Player
  (Totem Movie Player 2.32.0) which installed with the 11.01 Natty
  Narwhal upgrade that I did yesterday evening. The previous version of
  this application had the Flashplayer plugin installed and working
  perfectly. Now, on this new version, I can only see flickering pieces
  of the video images when I press the F11 key repeatedly to go between
  full screen and window modes, as if a black overlay is blocking an
  underlying image from being viewed. I also just tried playing a
  regular (non Flashplayer) MP4 video and that encounters the same
  problem. Please advise a workaround. Thanks in anticipation.
