I'm looking for a PVR that does not require a subscription and does not needs to "phone home". I will only use it as a regular VCR. I now I will be missing on the great features that the TiVo and ReplayTV services offer, but I have no phone line connection where this unit will be operating. Is there something like this on the market? Panasonic has a model that fits my requirements BUT it's a TV-PVR combo.
