Since your tuner is not being recognized you should first go over to  
the IVTV site and see if there is any information on what is likely a  
new tuner type, in other words you have joined the Hauppauge Tuner-of- 
the-Month Club.

Often you can set the type to a known one which is close enough to  
yours to work, the IVTV site may have info on which type to try with  
your particular tuner.

If the IVTV site has no specific info, I would try type 50 first, as  
this has apparently worked with some of the new tuners out there. If  
this does not work you will have to use trial-and-error to see of any  
of the other known types will work.

Not great news I know, but it could be worse.
