DOne major set back that the TF-7700 has, is the true number of TV channels it can store, the maximum number of TV and Radio is 5000 channels.

Do not be fooled into thinking this will be enough, as the true number of TV channels that can be stored, is as follows:-

TV 3500 is maximum number of channels that can be stored
Radio 1500 is maximum number of channels that can be stored

Why on earth they have decided to do it this way is beyond my comprehension, it is nothing more than a waste of resorces, as the majority of users will want access to as many TV channels as possable, only the minority will wish to use the receiver as a radio.
