Which model of HDHomeRun are you using? Some of the older ones aren't DLNA capable.

HD Homerun Dual for me and I had that thought too, but haven't looked the specs up on it yet.
Not a big deal as I just recently reconnected it to play with Plex dvr after I got an offer for Lifetime Plex Pass. I was just looking after today's post about it. It does work very well with Plex DVR though, should I need it as a backup to my Tivo's
EDIT: That's it. I have the HDHR3-US models, no DLNA support. HDHR4-2US adds support for streaming TV via DLNA/UPnP
