The lower half of the screen is a black box on one channel
It is an Advent DV2418A, 24" flat color Tv/ DVD unit. While commercials are on, I get the full picture, and nearly all channels are full picture, but one channel, no matter the time of the day, the black box appears in the bottom half of the picture, about 5 seconds into regular programming. On another channel, during a short period of the day, we also get the black box. I suspect a programming problem in the remote, but I have no idea how to re-program it.

go into your menu and find closed caption, someone has accidently set the closed caption mode to text, when the on screen display of channel or volume goes away the box appears. turn off the closed caption feature or switch it to something other than "text" mode, and your box will go away.
This type of problems and some OSD problems are occurs due to microprocessor over modulation. One option is there. That is if you have any child lock or keypad lock or frontpanel lock. First locked the system. Now check your problem arise. If it is not OK. Otherwise try to find nearby any radio frequency cable across in your tv. keep away that cablewire also. your problem solved. Even you get Call your nearst service provider..
On your remote should be a button called TV caption or text. Turn off the closed caption as someone hit it and turned it on by accident. If its not on your remote, then it is in the menu. Good Luck
