These *might* be contributing to the problem.  I have noticed that the 
cx23416 encoder doesn't always handle every possible combination of 
resolutions correctly.  You might want to start with something known to 
work (e.g. 640x480 or 320x240) and then once everything else is OK at 
that resolution then you can try a more interesting resolution.

A while back I did some experimentation with resolution settings and 
came up with an algorithm that seems to more or less predict "bad" 
horizontal resolutions.  It is far from perfect but it might give you 
some insight with this issue.  Check here:

(With that said, I have not run 352 through that to see if it's "ok".  
The point here is that I already know that the cx23416 seems to be 
sensitive to the chosen encoding resolution and that this issue might be 
an aggravating factor.)
