Not sure I've ever had to do it, but a colleague uses an exact 50000000 bit rate which gives a 1668334 buffer and frame size of 208541 if all figures are rounded to integers. These files have generally been accepted the other side of the Atlantic. As I've said before, the coder has got to reconcile a conflicting set of integer values when dealing with NTSC frame rates. It would be itneresting to diff frames made using the values above to those made using your values derived by working back from the exact integer frame size instead of forward from the bit rate. > [...] -- Tim.
