There's a simple tool filec in 
http://svn.xiph.org/experimental/derf/theora-exp/tools/ that can be used 
to compare the output of two dump_video runs and pinpoint the 
location(s) where they differ. The only more complex debugging tools 
I've been using are "sprinkle the code with printf()s" and diff, but I 
guess that's a little bit harder on an FPGA.
