Will Plex be able to efficiently use tuners? E.g. will it be able to schedule itself to record two shows using a single tuner if they are both on the same MUX?
If you look at the UK TV MUX lineup you’ll see it would be possible to record a lot of channels at once with only a few tuners. In MythTV I can record pretty much all UK TV with ~6 tuners.
Interesting question, I suspect the the HDHomeRun won’t be able to do this since it’s transmitting the channel over the network. Maybe if/when local tuners can be used it could use the same MUX data? I’m not a HDHomeRun owner, so I’m just guessing.
Thanks for clearing that up, I wasn’t aware the HDHomeRun had that limitation. I thought it was the network tuner that had it all 
I’ll avidly await IPTV support or local tuner support.
I don’t think there is such a limitation because MythTV does this and so does Silicondust DVR. The feature just has to be implemented. In both cases, I was using the same HDHomerun Connect that I am using now with Plex DVR.
I have confirmed that with 2 tuners, if I schedule 2 shows that are on the same MUX and then schedule a 3rd show, Plex DVR reports a conflict.

but does it physically use both tuners while recording is taking place, or is the HDHomeRun hardware smart enough to know it can just use one ?

I can positively confirm that with MythTV. I ran into multiple times when with 2 tuners I was able to record 3-4 shows at a time.
For SD DVR, I read it was doing this. The feature was added to SD DVR shortly after they added 30 seconds as the default pad time before and after a show. The default was sucking up extra tuners just for the 30 seconds of overlap. It’s possible the feature they were talking about was only for overlap on the same station? I will verify it on my SD DVR recording primary/subchannels and see how many tuners get locked.
I verified that the SD DVR does not share tuners with sub-channels that are on the same muxed channel. I recorded 13.1, 13.2, and 13.3 at the same time. Three tuners were consumed.
This verifies that the overlapping feature for pad time that I previously mentioned does not take sub-channels into consideration.
Since MythTV does it, but SD DVR does not, using the same HDHomeRun, it’s down to implementation of the feature on the DVR. The network tuner is not the bottleneck.
That’s very promising, I thought I remembered talk of it being possible back in my MythTV mailing list reading days. So now it’s just down to the Plex devs being smart enough to code it. Or they could go the easy option and just support IPTV and I could expose all the channels from the MUX over IPTV and advertise them with SAP.
Is there an update to this? This is an important feature and the only thing that keeps be from being able to consolidate all media related processes in plex. DVBviewer does this fluently too.
