Hi, I got my second TV Tuner this afternoon (another Hauppage WinTV-HVR 3000). Put it in and fired up DVBLink set it all up in DVBLink. Retuned WMC. Copied ACamd from my plugins folder of first tv tuner and pasted into second tuner. In the second tuners cardclient.conf I changed to viewer2 and password2. Made sure OSCam had 2 viewers set up. Cranked open WMC tried to view a Sky channel and nothing, blank screen and no viewer connected on OSCam.
So it is obviously a problem with ACamd or DVBLink. It's stopped talking to OSCam since I put the second tuner in.
What are your config files like when running two tuners?
