thanks
i checked those out

i guess my "answer" is no there is no way to tell exactly where a break point should go
after all it depends on how long the movie is, how big the data rate is set at
i guess the easy way is to try and look at the overall size of the project for example if its 6gb and 1.5 hrs
the 4gb (3.9) mark would be around the 1hr mark
