QuickMediaFormat
Note:
The mpos purge and the variable QuickMediaFormat are available by
default on DP 6.11. For DP 6.0 it requires one of the following patches or
their successor. Neither the mpos purge or QuickMediaFormat =1 is
available for DP 6.1. DP 6.1 customers should upgrade to DP 6.11 for this
functionality.
