Is there any way to make an R22 receiver record in High Def, even if it's hooked up to an SD Television? I have the blue light on the front on 1080i. I have the resolutions under HDTV on 720p and 1080i (480p unchecked) and it still won't record in HD. I obviously can't watch the HD content on the SD tv, but I would like to watch the HD Content from the R22 on my HR23-700 via MRV. It would be like having 4 tuners on my HR23.
