Well, I tested it at my brother's house again and it works! Can you believe that!? Ugh.....well, I've given up. Contacted every manufacturer's technical support that I could and read every manual that I can and contacted every expert on the subject (you guys) and decided that my TV does not like my Dreamcast. Period. I'm going to buy a VGA-To-Whatever will work or just wait until Friday since my CRT monitor is getting upgraded to a LCD Flat Screen. I'm going to test it with my Dreamcast within every return period until I get one that works.
I thank you again for all the help and I truly thank you Racketboy. I love the Dreamcast with VGA!! (Seriously! My brother and I stayed up most of the night kicking our friend's rear ends in Soul Calibur in beautiful 480p :-p)
