DIRECTV HR10-250 HR10250 High Definition DVR Upgraded to 870 Hours – WeaKnees.com While I probably wouldn’t advise anyone to buy the HR10-250 right now as DirecTV is converting their HDTV to mpeg 4 and the future still seems to be up in the air for this unit, it still is pretty cool that through Weaknees (the hacking TiVo specialists) you can buy a full one terabyte unit. One terabyte PVR — I like the sound of that.
