However many of the problems are due to other manufacturers not providing
Vista compatible drivers.

The drivers for which the manuafacturers have to pay Microsoft for a
"works with Vista" stucker, before they'll allow them to installed on
it.

Anything remotely media related is now horrendously messy to write for
(which is the reason Nvidia are still struggling to get one working !)
due to onerous conditions of a "protected path environment", bit-
flipping (which is likely prone to being affected by something as simple
as a mains spike), enforced shutdown of any type of output that might be
used to copy media of any sort, and degraded video / audio of any non-
protected path hardware.
