I think only having the “Search” option is limiting. Many times the title of the show I’m trying to record doesn’t match the name I think it should be. Special events, sporting events, etc. fall into that category sometimes. Also, much of the time time it’s nice to find out what’s on TV later tonight, tomorrow, etc. that I may want to watch or record.
Also, I agree with the other poster that looking for what’s on can be cumbersome at times, especially if the channel you want is not in your Favorites and you have many channels available. I can see an OTA setup being easier to navigate with a limited number of channels, but for those of us with cable it becomes a bit more difficult.
I understand there may be licencing fees for this so this may fall under the monthly fee category. This is something the average consumer has come to expect so adding this feature as an option is only going to grow your user base.
