RandR (not 1.2). For this specific behaviour, as this happenend with the
last head version of the xorg-ati-git version prior to the merge of the
randr-1.2 branch. But the xorg driver emulated an Xinerama setup.

There was a bug with the head version, that disabled XV on the second
head. That bug was fixed (as in head on sunday afternoon).

But this should not be a problem, as the resolution is changed and AFAIK
this is not possible with only XV, so the basic question is: why does
totem try to change the resolution? As there is a XV Extension, there is
no reason, because the grafics adapter is capable of scaline the video
fast enough to show it in 1400x1050 on either head...
