Let me put my unsolicited €0.02 in. My mindset is pretty hackerish as

is what it is, and it is a nice building block for many jobs. If I
wanted to build a vdr, I'd either let the raspi run permanently (given
its low energy demand) or get a Pico PSU powered mini itx board with an
embedded CPU, like one of the low-power (4.3-10W) celerons, and let it
wake up and shut down when needed.
That sounds reasonable. On any x86 or x86-64 hardware from the past 15
to 20 years, you can expect "rtcwake" to work. I will try to get around
to testing that part of my script soon.
One thing that I am somewhat proud of is the Systemd configuration to
have VDR start up automatically when a USB video storage drive is
plugged in. It is in a sense turning a deficiency into a virtue. Yes,
the video storage is a discrete component, but you can easily swap
drives, with no extra user interface needed beyond the USB cable and the
power button on the remote control unit. Such pluggable storage might
also be useful in a small form factor PC setup, if you want a quiet
system and need access to more storage than a single SSD can offer.
I just updated https://www.linuxtv.org/vdrwiki/index.php/Raspberry_Pi
with a few more options for each category, as well as some pictures of
my setup.
I also uploaded pictures of a disassembled Hauppauge remote control unit
at https://www.linuxtv.org/vdrwiki/index.php/Remote_control in case
someone might find it useful, for taking apart and fixing theirs.
