The technical aspect of this problem has piqued my interest, and also got me a little confused. Did the OP see an actual video/audio advert for the Playboy channel, or an ad for the channel plus the receiver's "Buy Now?" banner, or just the "Buy Now?" banner on a blank screen? I don't utilize the porn channels but have noticed that, unlike other PPVs, they do not include visible previews or commercials for the service. I would imagine the Playboy Channel would also conform to that standard. I'd love to hear a technical explanation of how the LNB or multiswitch could be at fault for this kind of "channel switching" problem. I don't see how it's technically possible for the LNB to cause this kind of problem; it just passes the full received spectrum down to the receivers/multiswitch. I suppose the multiswitch could send the incorrect polarity down to the receiver but I dunno how that'd cause a different channel to show up. I guess it could have been a local ad insert placed on the wrong channel, but then in 10 years I've never seen a Playboy TV ad on any D* channel that I can remember.
