I think you might want to be a little more careful in your use of the
term 'digital'. DirecTV-like satellite, 'digital-cable', and over-the-air
ATSC are all digital signals.
I believe you are out of luck in terms of receiving either of the
first two directly. You'll need a tuner/decryptor which are only generally
available from the companies involved.
OTA ATSC signals, on the other hand, are totally in the clear. The
HD-2000/pcHDTV card at http://www.pchdtv.com/ seems to work quite well. It
just dumps the raw MPEG-TS stream.
It is my understanding that OTA ATSC signals are not slated to change
format for the foreseeable future, so a similar card should continue to work
indefinitely. (Of course, the MPAA will do all they can to change that...)
