Playback Oddities with Final Cut Pro

Hello.  I am having quite a hard time in FCP.  I am relatively new to the software and platform.  I have the workstation hooked up as follows: i have my laptop hooked into my vx2000 camcorder and the camcorder hooked into a television for broadcast playback quality controll.  I created a seqence about two weeks ago that looked wonderfull, and when i played it back in the viewer, the same viedeo in perfect quality played back on the television.  This is how FCP should work.

Since then, i think i messed with some setting somewhere, but my beautifull playback ability has been destroyed.  I create a new sequence, add my clips and save the sequence.  Then, when i play back the video in the viewer, it is very jittery, sometimes telling me that frames were lost, and on the television, only the first frame of the sequenc is shown, not the running video.  Obviously, the problem is that i've changes some setting that i cannot figure out.

The kicker is that i can open the old "good-running" sequence and it still plays perfectly.  If i load the new, not-playing-back-correctly sequence into the good-playing sequence, the new footage plays as good as the old good sequence.  if i load the good old sequence into the new-bad sequence, the old good footage won't play back, so it has to be some kind of sequence setting.

this setting has permiated the new sequence settings because any fresh, new sequence that i create has the same problem.

I've gone through tons of settings to find something dissimilar between the good play back sequence and the new bad play back sequences, and they all look alike!  Please Help!
