TS file format: no audio with bs player 2.35

[fre]

Hi,

I use mediaportal to record programs from TV + bs player to watch them.
Recently, this software only allows the TS (transport stream?) file format for recordings (they used to support mpg-file format in previous versions)

When I open such TS-file, the problem is that my bs player 2.35 does render the video correctly, but I can't hear any audio. Other programs like VLC have no problems with the audio. In the past, my bs player did not have such problems with mpg-files

my question: what can I do so bsplayer gives correctly the audio?
is it a matter of installing the right codecs? so yes, which ones?

any support is appreciated.
kind regards,
fre
