HOW COME WHEN I PUT ON A DVD THE PICTURE & SOUND IS GREAT. BUT WHEN I SWITCH BACK TO SATELITE TV THE PICTURE IS NOT AS GOOD AND THE SOUND DROPS SIGNIFICALLY. COULD MONSTER CABLES HELP?
Cables do in general not make a huge difference, with the exception of very low quality or slightly broken ones. You probably have a setup problem, or maybe much better connections (RGB, component) for DVD.
BTW, it is customary in most forums not to use capital letters all the time.
