My Dad has a DirecTV TiVo R10 (I know...still in the non-HD world). It's been on his account along with 2 basic DirecTV boxes for about 7 years. He bought another R10 off ebay because he thinks the 7-year old one has been getting flaky. Not quite sure how to add it to his account. He would like to replace one of his basic non-recording DirecTV boxes with this "new" R10. Can we just move the access card from the basic box to this "new" R10 and then call DirecTV to get it paired/activated to that box? I saw elsewhere that you can buy a new access card from DirecTV for $20, but if he's going to deactivate a basic box from his account, why not just move the card? Thanks!
