It's interesting as I have seen the exact same thing on my Bolt but I didn't think it was a drop-in Ad. I thought there was a bug where it was playing the beginning of another random show and almost all shows play a couple seconds of the commercial before the start of the show I ask for. I guess I never let the ad play more than a second or so before I hit FF and it went away. But I've seen it happen several times in the past week or so.Feel free to download the video and host it yourself. No ads in the guide.
