That's the reason I like to record the shows... you can use fast forward to move through the commercials if it is recorded. However, if you use the "catch up" function for Comcast, sometimes the commercials are still there and you can't fast-forward past the commercials! However, I've noticed the commercials are not as long when you use the catch up function. The best bet is to use the DVR function to record it so you can blast past the commercials. In the old days, we had a remote "clicker". Evidently it used a sound wave to change channels. Once in awhile, my mother would be moving around pots and pans in the kitchen and the channel would change due to the metallic sound of the pans and pots. Weird.
