The HR10-250 is notoriously bad for its HDMI output port. There's a company that fixes them. They advertise on the web. Also, there is a newer HDMI card that apparently works fine. Mine went bad, and they sent me a new one (refurb actually - this was almost 2 years ago) and it's HDMI port also didn't work. I sent my old one back to them. I finally gave up, sent off my HDMI card and paid a $100 bucks to have it fixed. Worked ever since. DTV didn't do a good job of support on these, prolly because they were working on their own which is now here. Still, this is the best DTIVO out there if you want HD.
