We're dropping Comcast Cable, want to do OTA HD via antenna (mainly live as I use Boxee for recorded video) on my two Mac Minis on an Airport Extreme network (wired Ethernet)

Best option? HD HomeRun seems to allow 2 networked macs simultaneous access? Any disadvantage to HD Homerun vs. something like the elgato EyeTV hybrid? Does the Homerun require EyeTV software at an additional $79? Will I still get 5.1 audio with either option? Will my Harmony 890 remote control this option adequately?

Thanks in advance.

Dropping cable and going ATSC with a Mac already being discussed here:
