Robert, this has always been the case with direct rendering.. The
solution is to render to a analog hdtv screen, which happens to
be plugged through a frame grabber. The HD-PVR is also a very
affordable alternative to a frame grabber :)

The traditional low-budget alternative is to use indirect rendering,
which is only well supported on SGI's... Erm, I believe nVidia may
have a passable implementation of it these days in order to support
the Composite extension used by many modern window managers. The
problem with this is that indirect rendering is slower, so it won't
behave as well as the real thing.
