I believe the only 2 tools that can extract ATSC EPG information are MythTV and DVBStreamer (not DVB stream).
I haven't any experience with MythTV but I can say that DVBStreamer does appear to work with some US stations and is being used by several people to extract the EPG for use with Freevo.
Heres a link to a simple script to use with DVBSTreamer to update then extract the EPG information for all known/found services:
Finally there was another tool, pchdtv, which the author removed from the web sometime ago but might be worth a google for.
Disclose: I am the author of DVBStreamer.
