The HDHomeRun is a networked dual HD tuner device for shipping programming around your home computer network. Currently designed to work on Linux or Mac operating systems, the HDHomeRun receives OTA and/or unencrypted QAM via RF coax inputs and transmits content via Ethernet. Support for Windows MCE and BeyondTV is planned.
EngadgetHD writes: If you are in the market for dual ATSC tuners for your MythTV setup this may be the way to go. The network-enabled device allows you to add as many tuners as you want without being limited by the number of PCI slots in your PC, which opens up opportunities with small form factor computers like the Mac Mini. Priced at $169, you will have a hard time buying two ATSC tuners cheaper.
