Hi,

 Just recieved a used 7200 from in-law who upgraded to HD.  Can I still use this DVR?  It has

a yellow card inserted in the back.  I currently use a standard non-dvr in one room, and a 501 in another room.  Obviously I like the 501 and 7200 due to the no-fee grandfathering by Dishnetwork. Please advise on how to proceed...

 Thanks,
