There are TVs and VCRs with this, too. It's some extra guide that is for OTA TV, basically like the cable guide channels, just a list.

If you are looking at DVDRs as a time-shifting device, you should probably concentrate on Panny since they have DVD-RAM capability, or models with built-in HDD. If you are just looking to archive movies, don't compare it to Tivo or similar, they have different uses.
