hi prog,
today reinstalled progdvb 5.15.2 then removed the file "empgpdmx.ax"
and it seems everytihing is ok now.
no blackscreen and no sound problem anymore.
ProgDVB 5.15.2 is a stable version for me now
P.S. i have also update Elecard MPEG-2 Decoder&Streaming Plug-in for WMP to version 3.6.80523 before i was using version 3.4.70910
P.S. there's only one bug
if two channels are under different providers/categories and i fold out this category progdvb automatically fold in one of the categories so if i want to switch to another channel each time i have to fold out that category this happens only on this version (5.15.2).
