I currently have the 722K. I know that if I am recording 2 live programs, I can watch a pre-recorded DVR program but I cannot channel surf live TV.
I am thinking of upgrading to to Hopper/Joey system so I can have HD on my second TV.
I understand the PTAT feature with the new Hopper will allow me to record 4 prime time shows at once. From what I've read, it uses one of the three timers in the DVR.
What I want to know, if I have the Hopper/Joey system, will I be able to record two channels at once, and still have the availability to channel surf live TV?
Will the PTAT feature have to be disabled in order to do this?
