New customer (5 months) with recent installation. In Living Room, HR 24-500 and AM21 off air tuner. In bedroom, H25-700. My questions: 1. on bedroom H25, I cannot pause, rewind live programming, is that to be expected? I can however use those functions when playing back recorded content. 2. is H25 the latest model for what I'm using it for? 3. is HR24-500 latest model short of installing genie? 4. I've seen this answered in earlier threads but just want to make sure...the guide recently eliminated an off-air channel which i know continues to exist (cable carries it). Therefore I cannot access channel via guide. Prior to that happening the guide always was unable to identify content so I had to manually record show. Is that the reason no longer shows because directv does not have programming content? 5. My former DISH dvr allowed me to rename title of recorded program, does HR24 have this capability? I cannot find any reference to it. Thank you for any guidance.
