I,m going to upgrade my directv service to HD. My question is currently I have the directv tivo and love it, but I DO WANT HD NOW, having to go with directv dvr has brought up some questions to me, most everyone say's directv dvr isn't as good as tivo, but when I read the discription of the dvr it sounds like it's the same as tivo , has season pass, menu,ect... what are the detailed differences that make the directv dvr not as good? is it reliability,different features? never have heard a clear detailed review of why it's not as good. switching soon and getting a little nervous about losing my good old reliable tivo. any feedback would be helpful, thank's.
