[Fyi (and referring to my earlier posts about the non-functioning of DSP-filters) I substituted bplay.exe and bsrendv.dll in my existing installation by old versions and then both DSP plugins and Dedynamic did work!]
However that is not the reason and subject of this post, but it is ... just to let you know that build 501 is available as a nightly build. :P It contains an additional .dll.
There is an additional TAB in "Preferences" named "DVB broadcast client" where you can define MPEG2 video/Audio decoders.
Further equalizer is not greyed out. Didn't check yet whether it works.
(DSP plugins still do not work, nor does dedynamic filter.)
