Based on the stream address you're using, it appears that you're setting up an HDHomeRun Prime. While it takes a little more configuration, I have a small patch that allows you to use Tvheadend's native HDHR driver to tune the Prime. The disadvantage to this is that there is no automatic adding of muxes, but instead you must manually create a mux for each channel you wish to tune. Also, service names are not detected, so the only reference when mapping channels and assigning EPG channels is based upon the cable channel number. Also, streaming over HTSP only seems to work when you use a transcode profile to wrap the stream in an MPEG-TS container.
Even though those seem like quite a few negatives, there isone big advantage: UDP/RTP streaming. This means that streams from the Prime to Tvheadend are streamed over UDP, which is much better suited than HTTP streaming over TCP. With TCP, every packet must be confirmed, which means that packets are not guaranteed to arrive in order; this can lead to quite a few continuity errors, especially when recording multiple streams.
Another benefit to using the HDHR driver is that Tvheadend will receive live information about the stream, such as your signal status and signal quality, which otherwise you can only view from web interface of the Prime itself. Additionally, if you have multiple Primes, you can reuse the same network; if you set up the Prime as an IPTV network, each device must be configured as a completely new and separate network because of the streaming addresses, whereas reusing an existing network means you just need to tell your additional Primes which existing network that they should use.
