TV Glitch

My wonderful 36″ Sony WEGA television has developed a bit of an issue in the last week. My cable box rebooted itself and now when you change the channels, the television determines that it is seeing a Widescreen image and then letterboxes the channel. I do not know if this is part of an upgrade to my cable system where it is automatically broadcasting in widescreen or if there is simply a bug in the TV. It is more of an annoyance than anything, I just hope it is not a symptom of something more serious since I can hardly afford to replace it. (as much as I would love to have a 40″ Bravia LCD 1080p television).

Interesting to note is that if I TiVo a program, it automatically looks normal. Also, If i turn off the cable box and then turn it back on again the channel appears normal. So who knows what the issue is.
