Until the devs can get their devices on v10 and attempt to track down the issues as it sounds like Roku isn't any help. I guess it really depends on if this is a Roku defect in firmware or something Emby can fix/workaround. It is almost like they are using users as beta testers as I can not really find anything on this as a official firmware update.  But can only speculate as I know awhile back a lot of us requested a beta firmware to resolve previous firmware issues.
