Well here is the problem, few days ago the picture from the NTL box starting to flicker, originally I thought that my TV was on the way out, either that or the video recorder, as my cable goes through my video. But now I have suspicion it is my box. As not only does the problem occur on certain channels but when i taped one of the channels with that problem on cable, it came out flickering on the video, and this problem did not occur while taping a terristerial channel through my video. Has anyone else had this problem before and is it deffinatly my Cable Box?
