Sorry,I found that I've not studied ewavr's movie_rec.c extensively and thought wrongly that it would be easy
to implement variable bitrate feature.It seems that lot of work has to be done i.e. figuring out which functions to
modify that are called from task_movierecord,then further modifying the functions contained in the function we
wish to modify. The structure of Task_MovieRecord has also been changed in DryOS so it is not easy to figure out
(for me) what to change.In short, I apologize for my ignorance and impatience shown so far!
