Will WIN7 MCE suport 2 x AverTV TwinStar PCI-E

Hi,

I understand that WIN7 MCE will support four digital channels at a time (XP and Vista only supported two). However, I have been told that it will only support one AverTV TwinStar PCI-E (with twin tuners).

Is this true or can I safely / successfully install two of these cards and record four channels at the same time?

Thanks,
Glyn
