WHY NO PICTURE FROM THE DISC INSTALLED FOR USE, AND SHOWN ON MY ATT TV..ATT REMOTE CONTROL APPEARS TO BE THE PROBLEM--WHAT SHOULD I DO? iT IS NOT A FAULTY DISC ATT REMOTE THAT IS GIVEN THE INSTRUCTIONS TO START. MUST BE THE ATT  REMOTE THAT HAS ALWAYS SUFFICED.. COULD YOU SEND ME THE INSTRUCTIONS TO LOAD AND PLAY A OWNED DISC AS IN THE PAST.  PERHAPS LOADING INSTRUCTIONS WITH THE ATT REMOTE CONTROL IS NOT FUNCTIONING, AS IN THE PAST YEARS. OR I MAY HAVE DONE SOMETHING WRONG IN STARTING THE PROCESS TO SHOW DISC WITH THE REMOTE.  INSTRUCTIONS REQUIRED FOR THE DVD TO PLAY IS NOT WORKING WHEN REQUIRED IN THE PAST.  NO PICTURE SHOWS ON THE TV WHEN START IS REQUESTEd. LEASE HELP ME.  [email protected] I REALLY  NEED HELP FROM ATT UVERSE IN THIS MATTER...OR THE REMOTE IS NOT WORKING AS IN THE PAST,
