RCA ATSC21 High Definition ATSC (Digital) Tuner with NSTC (Analog) Tuner
Competent solution for high definition video; Dont use on old NTSC tubes
The low price of the ATSC21 represents a reasonable buy for producing component video.  I had no problems receiving digital signals.  This digital tuner brought in signals that another solution had difficulty with.  The on-screen menu does not output to the composite, and presumibly the S-video, outputs which make it a poor solution for existing standard definition screens.  Issues: The box gets hotter than I would normally expect.  There is also no digital readout of the currently selected channel on the physical box.  I have not tested the DVI output.  Bottom line, the product works well but you might be able to spend more money and get a better interface and newer generation tuner.
