I remember trying to set up a PVR and getting pretty far using mpv and at. The system worked as long as it was left on. rtcwake was the bridge that was too far: Upon waking, recording started but ACPI errors occurred soon after, culminating with ivtv reporting the encoder had died. I never got past that stage, but it was a worthy try - and I learned that some bugs ain't never going to be fixed. Edit: It was an Arch setup from about 5 years ago.
