BBC1HD from TVHeadend playing BBC1 SD

Minisatip, shield server, with tvheadend and tvhProxy in between. Works perfectly, except plex keeps mapping 106 to 106 (BBC1 HD) and then playing 101 instead! This happening to anyone else?

If I play from tvheadend, it plays in HD - so this looks like a Plex bug.

Looks like it is a bug with the epg. If you just play the channel its HD. If you play the show, it requests the SD stream. Where should I report this? Happens on any tuner.
