I may have missed this announcement - but I have a HD HOMERUN QUATTRO and am so pleased to see a Roku Channel (even if it is beta) - you have to add it as a private channel via your account page after logging in on a pc - then click on "add a channel with a code"
N6MN9QC enter that into the box
Mine added instantly on 2 x roku ultras and a Roku 3.
Only LIVE TV works and its only compatible with some roku's.
Apparently some Samsung tv's wont play the audio as they don't decode ac3 dolby digital sound - but most other tv's, soun bars, amps etc should work fine.
