I am trying to provide my mother with DVR capability. Considering that she refuses to subscribe and pay for TV programming and that the off-air programming will soon be strictly digital, I am looking for a DVR box with built-in ATSC tuner for DTV off-air reception. I don't think that she would need HD capability at this time or in the near future so I'd like to find a cheaper, not HD enabled box. Could anyone suggest a unit? Thanks!
