Here is what I spotted on the companies page about this delima we have:
"Linux support for the WinTV-HVR-1600
Linux support for the WinTV-HVR-1600 is in process. When the WinTV-HVR-1600 is added to the growing list of over 30 supported Hauppauge products with Linux open source drivers, an entry will be made in the LinuxTV.ORG Wiki".
So we sit and wait for the Gurus out there to develope for us little people!
