CBS all access is not listed as an available source for DS9 and Voyager.
This seems like a pretty small thing except for it hinders the use of voice search to play these shows on CBS all Access.
I'm guessing that Roku would rather we use CBS all Access to view this content rather than say Amazon prime (the current default with voice search) since we subscribe to CBS all access through Roku. Further if you do use Amazon prime it forces you to identify yourself instead of just launching the show like CBS all access would.
Of course I could just use Google Chromecast which works great with both of these shows except for when I want to stream another channel or another show I don't have the options that I do with Roku so I'd rather just stay with Roku.
Thank you for taking the time to look into this.
