Streaming Netflix w/Roku or another device

[PMCH]

Does anyone else have this problem with their HT system? When I stream Netflix or any other streaming service through my Roku (their best model) it looks and sounds terrible. I have it wired directly into the internet and into the input of the Oppo 105D. I am very satisfied with my Oppo 105d when playing Netflix and streaming Netflix. I didn't order a 205 since it couldn't stream.
I am on the list of getting a 205 and am now considering having my 105D connecting via HDMI to the only input on the 205 so I can get the streaming services. Has anyone tried this? Does it work? Since my projector has 2 HDMI inputs for picture I can have the 105D and 205 send a direct signal. I am only concerned with the sound quality. Presently I have the Oppo 105D send sound out through the analog connections directly into my McIntosh MX136 and am very happy with the sound quality. Since the 105D doesn't do 4K I was planning on using the 205 for that. My projector does 4K.
Any ideas. It is ok to tell me that I am going about this entirely the wrong way. Thanks.
