hi . Running windows XP32pro and progdvb 6.82.1 professional every thing is ok with audio codecs when watching SD channels. for channels with AAC audio codec , progdvb plays audio by "LAV audio decoder" for example ( I can use many other codecs which is installed on my PC already but I am fine with this one) . problem starts when : I want to record channels which have AAC as audio , then the recorded file has no ausio stream at all but the video is ok . I have tried everything that you may think of . can anybody help me ?
