 All DirecTV-delivered local HDTV stations (outside of the NYC and LA network stations) are encoded in MPEG-4.The HR10-250 cannot receive the MPEG-4 local HDTV stations in these markets but can still receive over-the-air ATSC broadcasts in these markets.After a multi-year hiatus, TiVo and DirecTV are developing a new TiVo-enabled HD DVR that will be able to receive/decode DirecTV's current MPEG-4 satellite signals.
