We have an SD-DVR40 that I added HDD space to record up to 244 hours. It has 6.3e software. The HDD has a lot of show on it I don't want to lose. I know there is newer equipment out there and we have had this a while. What I want to figure out, is should I upgrade to new hardware? If so, can I just transfer hard drives to the new box? Is it worth it to upgrade the hardware to newer used equipment? If so, what model should I look for so that I can get the best experience and still run directivo, or should I try to get new equipment from DirecTV? We have a large HD ready TV, but I am not looking to upgrade to HD as of yet. The third sat is blocked by a large tree so I don't think I can get that at this house without taking out that tree. So what would you do if you were in this exact situation?
