It wouldn't tune the right channel!

Here's a new one for me. Ordered UFC66 online for channel 123 for Sat night at 10pm EST. Went to select it to watch live from the guide. Guide data was right. But tuning to that channel was giving something that was running the Showtime logo!!. It simply would not tune to the program the guide had listed. Since I set this up to record, I tried to tune it from the playlist and got black screen. My HR10 worked fine. I was able to find and watch it on the HR20 on a different PPV channel (one that I didn't order!) so I didn't have to send a house full of people home, fortunately. I probably should have tried a RBR, but since I found it on the different channel, I didn't want to press my luck. :nono2: :nono2: :nono2: :nono2:
