I've also found the following two TV listings websites to be the best and most customizable to replace cable's program guide offerings. Be sure to sign up for a free account to personalize the channels you want in your guide.
Zap2it (Wikipedia article), which can link to Tivo; and
TitanTV, which may be the most usable with a Personal Video Recorder like a PC-compatible TV tuner like Hauppage with its own software.
Also be sure to check the extent your HDTV's implement the required Electronic Program Guide, which comes across more fully over-the-air than on cable's no-box analog NTSC and digital QAM offerings. Try the Display and other buttons on your HDTV's controls, and you will likely find a description of the current program on the channel tuned in at that moment.
Here are some helpful links to the detailed schedules, with individual program descriptions, of some of the stations listed above:
WKNO HD & SD
Some of the network sites have full episodes up for streaming to your PC, tablet, or mobile device! Including PBS!
