Video insertion is described for unavailable content. In an implementation, a method includes determining whether a portion of each of a plurality of content items is available for output by a client and generating an EPG for output by the client. The EPG includes a plurality of cells, each of which describes a respective one of the content items. The EPG is configured based on the determining such that when the portion of the respective content item is available, the EPG includes the portion when output, and otherwise the EPG includes a video insertion when output that does not include the portion.
