I recently bought a Roku 3 in hopes that I could use the Slingbox channel and watch my Slingbox PRO-HD stream on my Roku, through the Slingplayer app on my iphone/ipad.
Unfortunately, when casting to the Roku 3, the quality is horrible and won't go beyond 480p -- this is the maximum it has been able to reach. Additionally, buffering issues occur on a frequent basis.
A few notes:
It looks like the issue is narrowed down on the way the device (iphone/ipad) "talks" to the Roku 3 and relays the stream. Not sure how the iphone/ipad, Roku 3, and Slingbox PRO-HD connect to eachother when casting to the Roku, and where does the video stream ultimately passes from.
Any ideas are much appreciated! May thanks in advance!
