I've done a lot of testing recently. The RPi4 is an excellent backend
with HDHR Quatro as a networked tuner. That gives you 4 tuners and the
CPU horsepower to handle the recording using a USB3 SATA SSD or even
The good news is the RPi4 can also handle 4 recordings and do the
mythtv-frontend at the same time. For me that's 4 OTA mpeg2 programs
while displaying a previously recorded program. The quality is quite
good for the video playback.
However a separate FE is slightly better. I've tested a RP3B+ running
LibreELEC (KODI) with the kodi-pvr-mythtv addon. I've also tested the
FireTV Stick 4K running the Mythtv-frontend and the Mythtv-leanfront.
Both are excellent.
So for cheapest do a Combo RPi4 FE/BE with a 1TB USB3 SATA SSD using an
adapter. For best leave the RPi4 as a backend only and use the FireTV
stick 4K as the frontend.
That's the cheapest I've found. Since storage is the same for any
solution, the comes down to $25 for the FireTV stick 4K and $100 for a
RPi4 4GB DRAM kit.
I'm parallel testing both my Core i7 Sandybridge backend with hard
drives again the RPi4 backend. Using the FireTV stick 4K and a Shield TV
frontend on both. No difference in quality of recordings or playback.
