You mention under Options > Filters > Advanced , you see the Ligos MPEG Video Decoder. Do you also see Ligos MPEG Splitter?
Anyhow, my suggestion would be to uninstall/disable Ligos on your computer 1, so that Cyberlink can take over.
If you don't like to do that, you could create a file "bsfilters.dat" and place that in BSPlayer's installation folder.
In fact, you will find a
sample-file for such .dat-file is already present there, named "bsfilters.sam".
You could copy and rename the samplefile to bsfilters.dat, load it in e.g. Notepad and then
remove the ";" in front of the line "MPEG2={9BC1B781-85E3-11D2-98D0-0080C84E9C39},CyberLink Video/SP Decoder"
and save it.
Please let us know if it worked.
