TV traditionally has worked. Moved to Mex, TV worked for a short time then deterioated to snowy/unrecognizeable, all channels being rec'd but appear as stated. Cable checked wi other reg tv;all is well wi reception. ??callup Media Center, click "MY TV" ; click "Live TV"; appears to be attempting to access channels and does so but unclear reception on all channels as discussed above. Have processed all settings as required; cannot rec clear picture. thanks for a resolution
