HD DVRs

If he/you are running one cable to an HR24 and recording 2 channels then your antenna is setup for SWM. You just need to get a SWM splitter (2 or 4 port), insert it in the current coax line and run one cable to your current receiver and a new line to your 2nd receiver. All done!

I guess so. I don't know the specifics.

Does this mean you already have a SWM set up?

Do you have a SWM or multiswitch LNB on the dish?
If you have a (multiswitch) LNB dish, you will need to run two separate coax feeds from the dish using B band converters at the HR24 receiver. If you only want to run a single coax you will need a SWM LNB on the dish, power inserter and SWM multiswitch installed in the rig. About $100 investment to swith to SWM. I am in the planning stages right now to put SWM in my rig.
I'm looking forward to feedback here as well.

I want to add hr24 DVR to an existing hr24 DVR.

Hi; What do I need to add a 2nd HD DVR to an existing single HD24 receiver?

Thanks

If you are talking about a DirecTV H24 (not a DVR, just single tuner) then that's all you have and that's that. If you want a receiver that will allow you to watch and record 2 different channels at the same time then you need to replace that box or add another (now 2 people can watch 2 different channels on 2 different TV's plus record). With the right antenna you could even update to the DirecTV Genie and watch/record 5 channels simultaneously.
