I was watching my TV yesterday in the split screen mode. One picture was from my HR34 and the other was from my HR24. Both receivers were tuned to the same station, MSNBC 356. Both tuner pictures were in real-time, i.e. no delay. I was doing this to check my PROGRAM GUIDE for each receiver and still watch and listen to the program in the other split screen. Then came a fade to black to a commercial break. Guess what? The HR34 screen had one set of commercials and the HR24 screen had another completely different set of commercials! Then after the commercials, a fade to black and the regular identical 356 program came back simultaneously in both screens. Anyone? It's been many years since I took LSD.
