* 90-degree phase shifts for DPL/DPL II downmixes. 
  (90-degree shifted IMDCT function?)

* 100-7000Hz filter for center and surround channels for DPL downmix.

+* If it is 2 input samples one with PTS and other without it the first 
  PTS may be lost.


+* Set timestamps at right position (first syncpoint at received buffer)
  Now it is possible that timestamps are set one frame earlier.
  When tail of previous frame is received then new sample is created and 
  timestamped with currently received input sample. But this timestamp
  is for next frame.

* SPDIF (MCFish[doom9])

+* do not hold sample in between Transform calls
+* set both begin and end sample timestamp

?* Save settings when Ok in config dialog pressed; re-read it otherwise;

+* patch for chineese version for dialog size.

* BSPPlayer?
+* ZoomPlayer?
+* Audio delay adjust
+* Dloby Pro Logic (II) mixing.
* MMX DCT optimization
* Disable speaker selection when not stopped.
