I'm having problems using the widescreen function on non-widescreen programs with a Sony Wega KF60WE610 60 in LCD Projection TV. On the programs/movies designed for widescreen, it utilizes the whole screen. However, on regular cable channels it leaves black bars on both sides. I want it to stretch into the whole screen. I have tried pushing the WIDESCREEN button on the remote, and a text comes up reading "Full", but it does not change the program to full screen. Any suggestions? Thanks!
