Ok....the 211 works super with EHD. and yes no add dvr fee.
I dont understand when you talk about the $17.00 rcvr fee.
If you only have ONE rcvr ie a 722, than there is no fee. You will have a DVR fee on a 722, but that's it
Hope that helps
The OP already said he also has a 722 in post 7. If he gets another, that will cost an extra $17.00 per month.
