i have analog cable, i want a atsc tuner that can pull in antenna HD channels, and tune analog cable channels, and output them on the same component cable

something like the satilite boxes, where 4 is cable, 4.1 is digital antenna, etc etc

just want both "tuners" on the same output...

Problem you are going to run into is most if not all current ATSC tuners don't have multiple inputs for an antenna and cable. You'd need an A/B switch and need to manually switch between sources and possibly re-scan depending on the box.

If you can locate an older Directv HD box (something other then the H10 and H20) or if your really lucky an LG 4200A you'd have multiple inputs and not have the switching problem.

HTL-HD has that, but i wasn't sure if they'd work without a access card or satillite signal

Some of the older ones will work without an access card, for example the Sony HD200 or HD300.

If the H300 can work without a card, the HTL-HD should too, they are the same box inside.
