I've found it very awkward to re-establish remote control of the set top box via Slingplayer for iphone, after the phone has gone into autolock or if I have otherwise put the Slingplayer app into the background. Usually have to relaunch the app. Sometimes I have to reset the Roku. If I just leave the phone unlocked with the Slingplayer app. running, everything is fine, but this runs down the phone battery. Is there an easier way to channel-surf? Thanks.
