Panasonic AG-DV2000 Mini DV VCR will not play large DV tapes

I'm told to add more information although I'm not sure what else to add. The problem is this: Large format DV tapes (not miniDV) do not play properly. It plays back with extreme dropouts and a ton of banding even though the footage on the tape is pristine. I have checked the footage on someone else's same exact deck and it plays perfectly, but once that tape goes into my deck...total garbage. Again, this problem NEVER happens when watching and/or capturing miniDV, only DV tapes. The heads have been cleaned so thats not the problem (plus those same heads play miniDV fine). Don't know what else to say because the problem is simple, but the solution seems unobtainable. Hopefully someone has heard of this before because like I wrote previously I'd seen someone selling the Panasonic AG-DV 2000 with my exact problem (only plays miniDV) but for a very low price. Thank you. I'm told to add more information although I'm not sure what else to add. The problem is this: Large format DV tapes (not miniDV) do not play properly.

Former advice is very vague...can anyone be more specific as to what the problem actually is and how to fix it? Even the tech's I've taken it to don't really know what's wrong and/or how to repair. I own a Panasonic AG-DV2000 and MiniDV tapes plays fine, DV tapes are loaded with dropout/banding on playback though. I know its not the footage on the DV tapes b/c I've double checked all the footage on another AG-DV2000 & it played perfectly. Basically does anyone have suggestions for what the actual issue/problem is that a Panasonic AG-DV2000 won't play back DV tapes cleanly even though miniDV tapes play fine. I will then take those recommendations to the "qualified technician" in order to facilitate the mending of the deck. Does this deck have different sets of heads for miniDV & DV sized tapes? Anyone know a number to call Panasonic so I can talk to someone and see if they'll know or fix the problem???
