...know why this tv which is hooked? to my DVR machine and prior to hooking up my dvr to the hd tv the tv ran really bad and with the dvr it is working alot better but I was wondering if I need a HDMI cable for finer tuning and to get rid of some fuzz that I get every once in awhile-or do I need a HDDVR to hook up to get a better picture-Can someone give me advice-
