Our Aura is SWMBO's box. For the most part she'd just like her films to all be in a folder, not strewn along a 100+ items list. There is no way she could/would want to go down technical routes like that.One solution to that problem would be to use the money you saved by buying the smallest capacity PVR and buy a cheap NAS. Then copy the recordings off the box to the NAS where you can control the file structure. Admittedly not a great solution if you mainly record in HD although it is possible to restore deleted recordings to the Aura they were made on.
It's a bit sad as the only real reason to drop the FOX boxes was the atrocious subtitle handling. If Humax hadn't fluffed that we'd still be using them.
The other (Freesat) box is our shared/'my' box and is mainly watch and delete, like you.
I'd like a folder on that for (eg) films, but I find streaming services are filling a lot of that space for me now, so the absence of that option is actually driving me away from broadcast TV. I'm not sure if that is the intention of Freesat/Freeview, so can't say if their plan is working . (I'm paying for ad-free on streaming, so that should annoy the 'Free...' advertisers )
