the transport stream format that MythTV uses to store that data is
something they do not support, unfortunately.

Interesting discussion and progress.

If the Sony Freeview tuners in the V and W series use the standard broadcast stream then perhaps the stream that is filtered out of 
the hhdhomeruns might also be played by the Sony TV's?

However the hdhomerun streams in .ts format and based on what's been said already the TV's are unlikely to play a native hdhomerun 
.ts stream either?  (Maybe some can test?)

This implies to me these Sony TVs also convert the live TV transmission into AVCHD before they play it.  (I am not clear on the 
difference however it seems there is one!)

Following this logic for the TV to natively play the standard mythtv stream, it would have to (in simple terms) go in via the 
antennae - and not via ethernet - where it needs to be in AVCHD form.

What does a DLNA TV offer ahead of a mythtv frontend?  The only thing I can see is that it lacks the mythtv frontend hardware - and 
also a heap of functionality that Sony have not brought anything to my attention to say that the DLNA functionality is going to 
increase much in the medium term.  That is to say it seems a mythtv frontend is going to be superior for some time to come, and the 
limits of these FE's are mostly related to the CPU and secondarily the video card also.
