Thanks for all the help and suggestions! I think I maybe wasn't quite clear in descriptions.
In refrence to the missing song book I had no misconceptions that it somehow just up and decided to leave the HD. I am totally convinced that the missing song book is a direct result of the customers intervention.....grrrrr!
Regarding the Mitsubishi HDTV it mainly is a consumer TV problem as usual. Some mfg's for some unknown reason decide they want to be hardcore with the input resolution required and in this case it is exactly the problem. Since a computer uses the entire raster the output from the video card is going to be overscanned. That is where programs like PowerStrip come in handy, allowing me to set specific timings for the videocard. However in the case of the Mits. it does not want to see anything outside of a very specific input resolution. I was hoping that maybe someone here had encountered a similar problem and had a fix. I will get it just takes some investigation and time on my part!
Thanks again for all your help!
