I am thinking of upgrading my receiver to an HD pvr from my regular HD one(6100) and some of the ones I'm considering buying don't have remotes with them.Are all the HD remotes with the pvr controls on them the same?I may sell the HD receiver I have now and I'm sure who ever buys it will want the remote so I'll have to buy another one if the receiver I buy in return doesn't have one.They should all be the same,the silver ones with the pvr controls,shouldn't they?
