There are three basic types of TiVo boxes, depending on the type of source. They are:
- Over-the-air antenna-only
- Both cable and antenna
TiVo BoltThe TiVo Bolt is the newest TiVo device. It supports UltraHD (4K) TV, and is the fastest, most responsive device. It supports both cable and antenna sources. The TiVo Bolt starts at $299 and includes the first year of service. Additional service beyond that first year is $15/month.
TiVo RoamioThe TiVo Roamio devices are the previous generation, but apart from the 4K support, have most of the features of the newer Bolt. The TiVo Roamio supports both cable and antenna. The standard Roamio is $199, plus service ($15/month). The Roamio Plus and the Roamio Pro boxes are cable-only, and run $349 and $599, respectively. Service is $15/month.
TiVo Roamio OTAIf you're cutting the cord fully -- that is, no cable TV service -- and are using only an antenna to receive TV signals, the TiVo Roamio OTA is designed for you. It's the cheapest TiVo box, priced at $50. The real expense comes with the $15/month service.
What About Streaming?All TiVo Bolt and Roamio boxes support online streaming. You can watch content from Netflix, Hulu, Amazon Instant Video (including Prime), VUDU, YouTube, MLB.TV, and more.
TiVo is primarily a DVR, but does support some of the top online streaming services. It's possible that for you, TiVo will fill the bill.
