2 weird problems with MPC

There are 2 weird problems with my MPC:

  1. Everytime I set some external filters in it, after several restart, they gone ! the external filter list is empty again !
    The only solution is for this, is to disable save setting to ini option, any other solution ?

  2. Every time I tried to load subtitle, it gave an error msg “change the renderer to dx9 or haali”, but I already set the output to haali and haali filter is running, very weird =(, and it just happened recently
