OK, the problem with the command line was the windows command line max
length is too small.  It should work fine in mingw if i can fix my
syntax (gst-launch complains about needing a queue).  As for ixion, I
can play that same VOB file in Ixion but the CPU usage is 100%.  while
playing it with gst-launch gives me ~1% usage.
