As I posted before, there is a pitfall to defaulting to the ota tuner tuner especially if your programing the timer for multiple recordings. Especially if you have a plain 722. If your recording a main network program, you can't also record a program on a sub channel. That's why I use the Dish feed of my locals for recording most of the time
A neat feature I just discovered is how to skip/restore future programs in your dvr times. Press the dvr button 3 times and you will see your "Daily Schedule" of programs in your timers. You can go over to the list, select a time and press info. There you can skip/restore the timer, see all the timers for that program currently in the EPG and several other things.
