I'm sure this has been covered previously, but I can't find it. I'm interested in implementing the video on demand feature on my Hr20-700 and Hr21-200. I understand this is done via my DSL internet connection. But it is really too disruptive for me to run cables, so my question is can this be done over a wireless connection. What equipment would I need at the DTV boxes to receive the download? If I ordered it from one box would it download to both boxes? Appreciate any advice.
