This cannot output DTS-HD through the Optical output as, according to Zappiti, there's a licence fee to pay, which they don't pay, so we don't get it!! Why don't you pay it Zappiti, as your streamers are THE most expensive around?! DTS-HD IS available through HDMI though, which is ok IF one has a receiver which can use HDMI passthrough (mine can't!!). So I'm stuffed. Although I believe that one can BUY a special HDMI adapter which splits the Video/Audio stream so one can take audio to a reciever seperately - this should be supplied in the box IMHO. Also, there's an issue with the Zappiti used with an LG TV as the TV automatically switches the HDMI ULTRA HD Deep Colour on, which one cannot stop, then the Zappiti will not show a picture - at all!! Only sound - but not even that if it's the aforementioned DTS-HD!! Maybe it could be solved if the mini had a Wired SPDIF output like it's bigger brothers, but it doesn't. But an AVForum member has helped (thanks mtenga) by directing me to the 'Developer Options' section in the Zappiti menu system, where one can turn off 'Deep Colour' there, which did solve the issue. Having Deep Colour enabled on both devices sends them into a head spin, and you get no picture! Apart from these issues - it's (or the bigger versions at least) a great streamer, with all the positives of the AVForum review of the Duo. Maybe the answer is to buy the middle version, for just several pounds more, which has wired SPDIF, although that model is considerably larger than the Mini.
