So I got onto my directv account today and found out I can upgrade to an HD DVR free of cost my question is will it work with the current setup that i have? I currently have an R22-200 right now. I noticed at check out the option to send the DVR to me with either professional installation or self instal. This is why im asking since it gave me those 2 options. Also what other extra charges will I incur on my monthly bill? I know the DVR fee will be on there (as it is already since i currently have a DVR.) Any help would be much appreciated.
