Sorry if this has been discussed before, but I cannot find a similar thread. My elderly dad enjoys recording TV shows and burning them to DVD. Previously he has been doing this with a 2005-era Pioneer DVD recorder and the onboard analog tuners with local cable service. My parents have recently moved and I've had DirecTV HD-DVR service installed. Now I think he will mainly use the Directv DVR to schedule and record shows, and just dub them to the DVD recorder through the AV inputs. However, I'm trying to see if there is a simpler solution, to schedule and record via an older DVD Tivo by having it change the channels on the Directv receiver (a new HR24). Then he can burn directly to the DVD on the same unit. So the question is: Can the older DVD Tivos - the 57H, 810H - change channels on the newer Directv receivers via an IR blaster, by having the correct IR codes? I wonder since those models are several years old and well before the new Directv units were shipped, but maybe the IR codes are backwards-compatible? I do understand the DVD Tivo would not record HD, but that the HR24 could output in SD, which would be fine. Also is it correct that those used DVD Tivo units, if I don't want to pay for monthly Tivo service, would either have 3-day (basic), 14-day (plus) or lifetime subscriptions, depending on what the original purchaser chose?
