Phillips HDR series

The Phillips HDR series were the first TiVo models ever commercially released, with the HDR110 releasing on March 31st, 1999. All of the models in the HDR series have the same features, the only difference is looks and the hard drive size. These TiVos are also referred as the "PTV" series. The model released with the biggest hard drive from the factory is the HDR612, shipping with a 60GB hard drive.

These TiVo models got their last guide data update on September 15, 2016 and lost all guide data, Search, Season Pass, and TiVo Suggestions functionality on September 29, 2016.

Trivia

 * These units can still be used for recording, but you will have to manually input date, time, and the channel, making these TiVos "dumb DVRs"
 * All HDR models can hold 2 hard drives
 * The Series1 line can only hold up to 2 160GB hard drives, making 344 hours the most hours possible.
