With these builds I think 1280x720 @ 1Mbit/s should always be safe.
Depending on encoding options 1280x720 at a few Mbit/s may work.
With overclock and the right encoding options you might get low bitrate 1080p.

It's my TV's built-in tuner I'm using, not a STB. If my TV (and I imagine 99% of other TVs, or else people would be rather unhappy) correctly detects 4:3 programmes and Kodi doesn't, I'd venture to suggest that Kodi is looking in the wrong place for the information (maybe technically one of the right places but not in the one that everyone else has agreed to use).
I've made a few short recordings of different channels and on none of them does Kodi detect 4:3 (or at least it doesn't switch the view mode to Normal, which is what I've set for 4:3). Even The Simpsons on Ch4+1 didn't this time, when I thought it did before but it was on Ch4 before, so maybe there's a difference between the two channels.
For the first two recordings I captured the transition between the adverts (16:9) and the programme (4:3) which on my TV auto-switches between the two modes but did nothing on Kodi. Touched by an Angel seems to be in some strange format, as on Normal it has black space above and below (this is with the TV in 4:3 mode) and I have to switch it to Original to expand vertically, which sets the Zoom to 1.09. When I play the other recordings, they all use Stretch 16:9 for both the adverts and the programme but when I play Touched by an Angel again it auto-changes back to Original, which I'm not sure how it's managing as the default is set to Stretch 16:9 and "Display 4:3 videos as" is set to Normal.

I gotta say video qualty for a given size is just insane, hopefully things can get for a better in a future.

I brought up the OSD and it looks to be skipping 10fps or so. The feed was 720p. I played a 720p recording and it did the same thing. I switched back to OMX and it looks fine. The OSD doesn't seem to show if it's skipping or dropping frames, but the video looks like it should.
I will do some more testing later with 1080i and SD TV channels to see if I can provide more information. I have to go right now though.
