We currently have a great HR24 w/AM21N yet the ability of the Genie to record five shows at once seems appealing. Since my wife likes to record different shows on our bedroom STD TV & STD DVR the Genie would be used only in our living room. Since I am by far not up to speed on the HR34 would it be ill advised to replace our ultra reliable HR24? Are there additional fees/cost and hidden caveats associated with this Genie in a box? Please tolerate my ignorance.
