Although it's jolly sensible to have
v5.7 firmware on a Vestel T810 (e.g. Digihome PVR80) after a region's DSO, not every TV mast necessitates its installation. As you've found, Sandy Heath is a mast which doesn't. According to
Digital UK's "Installer Newsletters", the 8K-related fix made in the upgrade from v5.6 firmware is to allow
"negative offset RF channels" in combination with 8K mode. That's to say,
v5.6 is compatible with 8K mode muxes if they
don't have negative offsets!
According to
Digital UK's "Trade View" for Sandy Heath, happily for you, the post-switchover Mux PSB1 doesn't have a negative offset - so that's why your v5.3 firmware is OK. The table also shows
no plans to introduce negative offsets to transmissions from Sandy Heath!
It seems for now there's no urgency for you to get the v5.7 loaded - unless you intend to move into another mast's coverage area! Tell any estate agents you register with
as a homebuyer, that only properties served by a TV mast
without negative offsets are of interest!
As a fellow Sandy Heath user, I've been anxious about the effects of the impending DSO on my PVR80 (with v5.7 firmware). Following retuning, I'm cheered by it being alright for live reception on the post-DSO "Mux PSB1". But I won't give it a "fitness note" until I've "pushed it closer to the edge".
AFAIK, the T810 suffers from the "tuning memory size" issue, no matter which firmware, whether on 2K or 8K signals. As a matter of routine, I use the technique below to work-around it. N.B. Between the two stages of DSO (i.e. now), follow the "yet to switchover" instructions
but in Step 6, don't Manual Channel Scan the last group, "Group 3".

As I've been able to overcome it, by a carefully designed tuning procedure which reduces the number of memorised stations, I now believe that the problem is due to the limitation of the recorder's flash memory size (not its "hardening").
Access Digital UK's guided Manual Retune page. By entering your address into the Postcode Checker panel on the right-hand-side, you'll obtain the RF numbers for each of the 6 or 7 Groups of Freeview stations from your particular TV mast. Note those RF numbers down (including the Group labels).
1. Unplug the recorder's aerial.
2. Run the Automatic Channel Scan. When completed, exit the menus by pressing the Back key - you should see a "No Signal" message!
3. Re-connect the recorder's aerial.
4. Run the Manual Channel Scan entering the RF numbers for a yet to switchover TV mast, of each of Groups 1, 2, 4, 6 or for a switched over TV mast, of Groups 1, 2, 3, 5.
5. In the Channel List, select each subscription/junk station in turn (i.e. TopUp Anytime/Shopping/Gambling/Porn) and Delete them.
6. Run the Manual Channel Scan entering the RF numbers for a yet to switchover TV mast, of each of Groups 5, 3 or for a switched over TV mast, of Group 4.
7. Exit the menus.
You should now find that the Digihome does remember the stations in its tuning memory during a period in Standby!”
