There was a non DLNA compliant hack which described all video as 'NTSC in 
MPEG-2 PS format', even for DVB (pal) AVC TS streams.

This hack has gone, and we now have support for telling the difference between 
AVC and MPEG-2, HD and SD and ATSC vs DVB standards. What's still missing is 
support for differentiating between TS and PS. Since all broadcast material 
uses TS, we assume that it actually is TS for now.

DLNA only supports HD in a PS container when the audio stream is also DTS, so 
in your case I'm uncertain what the behaviour would be. We'd fall back to 
specifying no DLNA profile at all, which with some players means no seeking is 

For now I think the simplest fix would be to offer a setting that disables DLNA 
compliance mode entirely. This means you get none of the benefits of DLNA 
features, but for the most part these are minor.

Even if I manage to implement support for determining that recordings which 
recording use PS and which use TS, recordings which are transcoded outside of 
MythTV will still be mis-described until you re-run a tool to 'fix' the 
description in the database. This tool is planned, but is not currently
