Review of Linux Compatibility
The Hauppauge Colossus is a video editing card for the PCI-Express slot. The card support among other things the recording of HDMI signals.
Until now no Linux driver is available for this card, hence no functionality of the card can be accessed by Linux. Alternatively it is suggested to use the model Hauppauge HD-PVR instead, which provides the same functionality but is connected via USB.
