The amount of storage capacity for programs is dependent upon the size of the hard drive inside the TiVo; different models have different sized hard drives. When the space is full on the hard drive, the oldest programs are deleted to make space for the newer ones; programs that users flag to not be deleted are kept and TiVo Suggestions are always lowest priority. The recording capacity of a TiVo HD DVR can be expanded with an external hard drive, which can add additional hours of HD recording space and standard definition video recording capacity. In September 2008, DirecTV and TiVo announced that they have extended their current agreement, which includes the development, marketing and distribution of a new HD DIRECTV DVR featuring the TiVo service, as well as the extension of mutual intellectual property arrangements.

TiVo Joins with Jaman to Deliver the Best of the Big Screen to Living Rooms Across the Country". Tivo.com. Archived from the original on November 22, 2008 . Retrieved November 1, 2008.The TiVo service is available in the United States, United Kingdom, Canada, Mexico, Spain and Taiwan at present. Over the years since its initial release in the United States, TiVo Series1 and Series2 DVRs have also been modified by end users to work in Australia, Brazil, Canada, New Zealand, the Netherlands, and South Africa. TiVo still uses the same encoding, however, for the media files (saved as .TiVo files). These are MPEG files encoded with the user's Media Access Key (MAK). However, software developers have written programs such as tivodecode and tivodecode Manager to strip the MAK from the file, allowing the user to watch or send the recordings to friends. In 2008, some cable companies started to deploy switched digital video (SDV) technology, which initially was incompatible with the Series3 and TiVo HD units. TiVo Inc worked with cable operators on a tuning-adapter with USB connection to the TiVo to enable SDV. Some MSOs now offer these adapters for free to their customers with TiVo DVRs. On 8 July 2006, DirecTV announced an upgrade to version 6.3 on all remaining HR10-250 DirecTiVo receivers, the first major upgrade since this unit was released. This upgrade includes features like program grouping (folders), a much faster on-screen guide, and new sorting features. Various capacities of external drives have been shipped since the product was initially released. There were reports of product reliability issues, [26] and a brief period of unavailability. [27]
