I have got one Nova-T stick working perfectly, have installed the other, and windows detects them both in Device Manager (and I've checked both are using BDA drivers). I've added one to the Capture Cards list in Media Portal, and it works fine, but when i click Add again, it says

No video capture card(s) were found, you won't be able to configure a capture card.

The only thing I can think of is that its somehow confused because I have to identical tuners? They are both pluged into a USB Hub which is plugged into the Mac Mini.

Any suggestions or help would be appreciated.

Thanks

Mark
