I cannot get my WinTV card to work with Ubuntu 12.04. The same card has worked in previous versions of Ubuntu, and I know the card is working because the PC has dual booting and it works fine in Windows. The card is recognised and shows up as BT878 Hauppauge /dev/video0 in applications, but I get garbage when try to use it. Are you able to help out?
I found my mistake, I was not selecting the correct video input for the card, so I was getting the video from an input which didn't have any signal. After the selecting the correct input (composite video in my case) I was able to capture the video.
