The driver send PES of size 2048 bytes or smaller to the firmware. So an
optimal PES size would be 2048 bytes (including header) or smaller. Of
course, you would want to start a frame at the beginning of a PES, so
that the PES before that is usually smaller than 2048 bytes, but
that's ok. You don't have to use padding. Other PES sizes should be ok
too, the driver repacks the PES, but it can only make them smaller.
