I'm looking for a more affordable option to renting a dvr to record the shows I like to watch. The time warner cable package I purchased didn't come with one like I thought it did. I've been researching some of the boxes on the market that allow you to record to a freestanding hard drive or a flash drive but there seem to be quite a few limitations. Anybody have a good experience with these recorders? Is there one you would recommend? Do dvrs from other carriers like direct tv or dish work to record on twc?
