tried banging the subdivs up to mad amounts but no help :s
the glossy is interpolated and subdivs are on 60 or so, using adaptive QMC 4/1 aa
and default QMC settings

[also sorry if the links are down, very up and down server atm]

Simon,
Dont use interpolation with glossies and animation.
If you uncheck interpolation it wont flicker

Yeap... Interpolated Glossy worked great for Stills, but is a bad idea for anim.
