If your DVR has an eSATA or Firewire port on the back, it is sometimes possible to attach a regular external hard drive for computers to it to expand the storage space. After formatting the external hard drive for the DVR, your DVR is most likely to restart recording TV shows into either its internal hard drive or external that you attached depending on which has more available storage space. Consult with your DVR's owner's manual. Note that you will not be able to take out the recordings from the external hard drive using a computer as the external hard drive has to be formatted FOR the DVR in such a way that the computer cannot see / access it.
