I have been succussfully running my Twinhan VisionPlus DVB-T card here in .au for over a year now. Recently I decided to get another tuner and went for a WinFast DTV1000-T.
By themselves each card works fine. But togther, only the DVT1000 card works.
Here is dmesg output for a boot with only the twinhan card installed (Linus 2.6.15 kernel):

With both cards in the machine, this changes to:

Ok, so clearly the twinhan card is not being detected anymore. So I tried
modprobe bttv card=0x71 tuner=4

Any suggestions?
