A keen observer over at DBSTalk noticed that the ATSC
tuner add on for the HR21
is finally available on DirecTV.com for purchase. This $50 accessory
will enable HR21 owners to tune into and record OTA HD
channels and is a must have for anyone who wants access to every local HD channel in their area. Although DirecTV caries HD locals in most markets, it doesn't carry all the HD channels in those same markets. As expected, it'll let you record two shows at once, but unfortunately it doesn't work with the H21 HD receiver (non-DVR).
