I am using a Hauppauge HVR-1600 tuner that is recording analog cable tv (NTSC). About two weeks after the initial install I recorded another show but when I went to watch it, it was just an hour of a blank red screen. When I ran mythtv-setup and went to the tuner card setup section I noticed it said ""Failed to open"" in the Probed info section on my tuner card that I had previously successfully configured. The configuration I am using is Video device: /dev/video0 and VBI device /dev/vbi0. When I looked at the log file for mythtv-setup and mythbackend I only see the few entries which I listed below. I also looked at syslog (see entries below) and from what I can tell the OS successfully recognized my tuner. Also, when I look in /dev I see three entries which are video0, video24 and video32. I have since upgraded to version 0.26 but mythsetup still does not recognize my card.
