Wow, if the lineup on that web site is actually correct for you, it would be a complete and utter shock to me. I've been in contact with Mediacom for now for over a three weeks, due to the fact that they can't provide me a channel lineup that is 1:1 to what I actually get inside my house. The listings at the site above for my zip, and also the surrounding towns, used to be dated Dec 9 and had errors from when they switched channels around back on Sep 1, 2009. Then, last week they "updated" it, except that the date now says ... March 29, 2010 (yes, in the future) and they didn't actually fix a single error on the lineup that I had been telling them about.
Also, they usually tell me to use the Zap2It programming listings, and not that link above, and TMS has completely different errors in their database that after four weeks I can't get them to fully resolve. They almost fixed it back in January, but in the process they introduced two channel errors. Then, four weeks later, they fixed those two new errors they created, but then introduced yet another completely new error this past weekend.
Apparently, knowing what station is on what channel is one of the most complex things we have to deal with in modern life.
