@Yaobing, Yeah I'm a bit torn between the two different options as I think they have potentially different uses (if what I'm thinking is correct)...
1) Traditional Tuners: (Currently) best for MC based Clients (all the goodies work and have for years) = best quality and flexibility, but you have to setup
2) New DMS Tuners: Easy to setup and as they are a stream direct from the HDHomeRun it should work on all clients (web, remotes, etc and regardless of OS) without MC needing to transcode anything. I presume you just hand off this stream to the clients? Downside is there is (currently) no processing done on MC (Video / Audio etc) so all the goodies from MC are not applied. Also that Green Corruption on SD Channels looks like an old bug from years ago.
