My longer-term plan is to transition to a mini-PC solution running e.g. OpenElec (disto based on XMBC/Kodi). that would be with PCI/USB tuners for DVB-T/DVB-S.
My reason for going HDR-FOX when they came out was that a PC-based solution was too expensive and there were no DVB-T2 tuner dongles. No doubt the situation has changed over the last 5 years.
Like BH and cdmackay, I have looked into a PC-based solution as an alternative but even just a pair of USB DVB-T2 tuners costs over £100 so a second-hand 'Fox is a better bet.
Between us we ought to be able to come up with a reference design, and if we all use the same platform and software it will help with support and give others something to follow.You can get a dual-tuner for about £80, but yes, it's not cheap, especially if you want DVB-S too, as I do.
Still, had the software been up to it, several years ago, I'd have spent the money doing it properly. But MythTV, then, seemed a terrible mess, so I gave up after a few months. I'm sure Kodi is much better...
We should go at least one better than HDR-FOX though - three tuners, four tuners?
Does an RPi have enough oomph?
