playing videos with mplayer causes diagonal tearing on fullscreen with
the xv driver, that uses Radeon Textured Video, even if it is played
step by step

the definition is not an issue as it appears always, as this example:

it appears perfect with the gl and x11 drivers

the problem appears with the default configuration, with KMS and
without composition, on an AGP ATI RV100 and AMD Athlon XP 2000+
the diagonal tearing is from up-right to down-left

it may be related to this bug:

if I run a composition manager (xcompmgr), casual horizontal tearing
appears, with xv, gl and x11 drivers, but this is another story
