Hauppauge Nova TD – USB stick now thinks it’s a mono unit

Having solved the challenge to install drivers for vista and the Nova TD stick and successfully recording one TV channel while watching another, Everything suddenly changed and windows MCE now only sees the Nova as a single tuner.

The only thing I can put this down to is the automatic updates as that’s all that changed.

The Device manager shows 2 drivers one Nova T and one Nova TD.
When I uninstall the Nova T driver Windows puts it back on at the next boot without asking permission.

Retuning MCE only finds a single tuner although Win TV 7 from Hauppauge lists the device as a Nova TD.

As I use MCE I would like to use it on a Dual tuner, can anyone offer a solution?
