You should try cold-booting the machine. This involves shutting the machine down, and '''REMOVING''' power from the machine. This forces the firmware to be cleared from the memory on the Hauppauge card. A warm boot won't necessarily do this. | You should try cold-booting the machine.

ivtv-firmware has no installation candidate
If when trying to install the firmware, you encounter an error similar to:
supermario@portablemario:~$ sudo apt-get install ivtv-firmware Reading package lists... Done Building dependency tree Reading state information... Done Package ivtv-firmware is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package ivtv-firmware has no installation candidate
This likely means you had a typo when adding the firmware repository to your /etc/apt/sources.list
Recheck /etc/apt/sources.list
and make sure that you properly added the repository that you are getting your firmware from.
