External Hard Drive DVR Recordings - DirecTV

I have an external hard drive that I keep DVR recordings on (I currently have DISH - I can move them back and forth - and can watch them from the hard drive). If I switch to AT&T and their DVR, will I be able to still watch & connect the external hard drive to their box?

This question, "External Hard Drive DVR Recordings," is about DirecTV channels, programming, equipment, and sports.
