HD channels without HD box?

Short of dedicated computer running some sort of media center + a CableCard + a CableCard device - I think you are stuck.

Most over the air channels now broadcast in HD.If you use an antenna you'll get a ton of local channels in HD.A friend of mine uses a rotational roof top antenna and he gets TONS of stations from all over New England almost all which are HD.An incoming cable line can also be used as an antenna.

PS.Bob,any antenna will work.One of the biggest ripoffs is the so called "hd antenna".The roof top one my buddy uses is over 30yrs old.
