I have cable and a DVR, and I love the DVR, being able to tape shows and watch them later. Excuse what may be a dumb question, but I’m not tech savvy. Can you use a DVR with Roku? Or does Roku eliminate the need for a DVR because you can just call up any program any time? Cable is so expensive, I’m looking for an alternative. But I don’t want to give up the ability to set the DVR for a show and then watch it later, or over and over again. Thanks for any help!
