I got the firmware installed in /lib/firmware and everything looks good, but when I run tvtime it says:
inappropriate ioctl for device /dev/video0
and when I try to run VLC it doesn't work and I get this in the dmesg log:
cx25840 7-0044: 0x0000 is not a valid video input!
but here's the interesting part (which is most tantalizing)
if I run
cat /dev/video0 > test.mpg
and let that run for a bit, aborting with a ctrl+c, I can play the captured mpeg perfectly with vlc with sound and video.
vlc test.mpg
edit:
so I installed mplayer with sudo apt install mplayer
and sudo apt install libvdpau-va-gl1 because it kept telling me that it Failed to open VDPAU backend libvdpau_va_gl.so: cannot open shared object file: No such file or directory
so I can run mplayer with:
mplayer /dev/video0 -vo vdpau -ao sdl
or
mplayer /dev/video0 -vo sdl -ao sdl
and it works, but there's a one second delay after I press a button on my tv box remote. One thing that's good is that the audio and video are always in sync (since it's an mpeg stream).
I think the HVR 1950 defaults to channel 3 which is fine because I'm getting an analog tv signal from my comcast cable box. So I'm not actually having to tune the HVR 1950.
