just want to be sure i understand a couple things involving an external hard drive with an hr20-100 or 700 dvr. if the dvr goes bad and needs to be replaced, all of the shows on the external hard drive that was connected to that dvr, are lost? in addition, those shows cannot be played on the replacement dvr? i haven't gotten the external yet, but the so far very unreliable directv dvr's sort of make me hesitant to build a 100+ hour hd library. i've had more directv dvr's go bad in the year or so that i've had them, then the 10 years with tivo prior. and yes, i saw the new tivo and directv announcement. yes!
