I have a Hughes HDVR2. Serval years ago I bought this used off of eBay, put two drives into it and used instant cake to build a nice DVR. When I built this I didn't get a new card from DirecTV. Not sure how I got this to work but I am really sure that this card came out of my other series two DVR. This unit is toast one modem has been going bad for a long time and now it makes hard drive grinding sounds. I have another series 2 it is an H10. It was replaced with a higher capacity unit. It is was working when disconnected but only has a GB drive. Yes H10 has an R I D number on it. Does it really have an RID. Can this card from my trashed unit be put into the H 10? If I reset the hard drive completely and put the card in it, isn't there a place on DirecTV's website to make it issue a reset? Thanks.
