I can connect my DirecTV or Panasonic Blu-ray to my M1 via component cables. Running Slingplayer Channel on Roku Stick, and pressing 'options' when content is playing shows stream bandwidth running low 5,000kbps and RES: 1280x720. Never hits 1080, and video on 48" LED looks soft. VUDU Blu-ray channel plays back fine at 1080P, I do not believe this to be a problem with my bandwidth (Comcast).
Is the Slingplayer Channel (app) on Roku Stick limited to 720P?
