new to this forum and very late for the party.. 
  
shame on me I own this little beast for month but just found now 
the time to concern myself with video mode. I was really shocked when 
I tried the recommended settings and ended in interlace trouble.  
  
After some test I found that shooting 50p converting with clipwrap  
and throwing all in a 25p FCP X project makes no visual difference 
to a 50i clip converted by ClipWrap (looks still interlaced!) in the same 
25p project. No visual difference either after export. 
  
For myself I switched back to 50p that gives me the chance of real slo mo too
