Thanks for all the info. I am interested in the RPi4 solution, but
still concerned about no GPU support.
<br>
<br>
I notice that Newegg has a low end 7th generation NUC for $138
(BOXNUC7CJYH1) thats with a
<br>
2.0 GHz - 2.7 GHz burst, Dual-Core Celeron J4005 and a UHD 600
Graphics. 4GB of ram is $18 (although I would probably go for 8G
at $36).
<br>
<br>
RPi4 with case +fan + power with 4GB, is about $85, so that
comparison in cost is $85 vs $156.
<br>
<br>
I presume the UHD 600 GPU would make use of vaapi (with
improvements under the new render).
<br>
<br>
Which solution would work better running as a frontend running the
master?
<br>
<br>
Right now the 10 year old Macmini FE/BE is running Ubuntu without
internal storage, root and media on a huge USB SATA disk. The mini
is only USB 2 while the disk is USB 3, so either RPi or NUC would
be a win.
<br>
<br>
(By the way, I run the HDHR-3 for US cable, waiting not so
patiently for the HDHR Prime 6.)

GPU which worked well for years, and I really want something
with a GPU that Myth supports.
<br>
<br>
From what I read there is no GPU support on the PI4, which
other than would be a nice price point.
<br>
<br>
I know a NUC would work, but they start getting pricey once
configured, and its not clear to me what the cheapest one
without media format limitations is. I know there are other
boxes in similar form factor, but don't know if there is a
better value than a NUC.
<br>
<br>
Storage is not an issue, I already use a large USB disk for
both root and the media on the mini.
<br>
<br>
It seems like even cheap phone/tablet SOCs have better GPUs
than the old Nvidia.

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 hard drive.
<br>
<br>
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.
<br>
<br>
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.
<br>
<br>
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.
<br>
<br>
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.
<br>
<br>
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.
