Oh wow. No, I did not know about that project. That looks like WAY too much fun. I think my wife would kill me if I got involved. I'm going to have to resist buying the hardware, because once I did I think I would spend all my free time hacking on it. I would actually be more interested in writing ATSC transmit code, even if I couldn't create it in real time (perhaps I could create a huge encoded stream and then send it), although transmitting should require less CPU than receiving. I have always wanted to test how different tuners behave in the presence of a variety of bad data, and also test compliance with more obscure parts of the standard (e.g. directed channel changes).
