When I first published my channel after a week Roku started showing lots of random ads. I was very impressed with what I thought was coming for me, but sadly I never saw a penny. When I decided to convert to the SDK model they killed the ads completely and I have been unsuccessful in getting them to stream even the suckiest lowest paying ad.. Just Something! Instead my viewers keep seeing the in-house Roku ads over and over which is a major turn-off. No response from Roku except the typical "we'll get to it eventually". Not the case. You're being ignored, period. If your channel isn't extremely popular, probably commercial, good luck with Roku's RAF system. Funny thing is, when you upload your channel for testing to your local box, random ads are served just fine using numerous "test URLs" provided a long time ago by Roku (and who's getting paid for these?) but the minute you publish, the ads are suppressed on the published channel. What I feel is that any time an ad is shown in full and the developer never got a penny for it, somebody got a penny for it.... the question is.... who.
