Cable bills in Springfield just went up. You can blame higher programming costs for that.

That's not the only frustration cable customers are running into. Many customers are waiting a long time just to get a high definition cable box.

It comes down to demand. People are upgrading, and Mediacom is having a tough time keeping up.

Right now, at least 200 people are on a wait list for an HD box from Mediacom, some have been waiting for two months.

Mediacom says more boxes are scheduled to come in, so be patient.

"It's not just Springfield, the cable industry is having trouble keeping up with the demand for the customers asking for DVRs, and HDs, and especially the HD DVR. That's like the holy grail right now," Mediacom Region Operations VP Larry Peterson said. "We've got three different manufacturers we use to try to get the boxes available and it just seems as soon as we get them in, they go out."

Mediacom is getting 8 new HD channels December 17th. They are WGN, TBS, CNN, Sci-Fi, A&E, History, HGTV, and Food.
