Description David Schleef 2008-07-30 18:16:51 UTC 
+++ This bug was initially created as a clone of Bug #537889 +++

...

This still doesn't fix it entirely with totem, for two reasons:
 - totem sets the values every time. We could fix that by not scaling things (or by only scaling things for use via properties, not via the colourbalance interface), but...
 - totem reads these via the colorbalance interface, and does its own scaling, with rounding errors.

...

See patch on other bug.

I can confirm the "colour drifting bug" and also that the patch in the other bug (together with gst-plugins-base from CVS) fixes it. Here are some other users having this problem:

https://bugs.launchpad.net/ubuntu/+source/totem/+bug/216820

Would be great if the patch was committed.
