Hi again, I've already asked this question recently, but I haven't gotten any response so far :( I can hardly imagine none of you has ever had lip sync problems with the kfir board, as I have them all the time on 4 different boards :-/ So, here it goes again: does anyone know how to adjust for lip sync problems, by changing a parameter in the linux kfir driver or something? I've tried adjusting the values for video_offset and audio_offset in kfir.c, which I thought would influence the PTS and DTS'es. Can anyone tell me what the unit of this number is? Judging by the calculation being done it has something to do with the 90 kHz effective clock for the PTS/DTS, but I've tried dozens of values and I can't really seem to get an effect. Any help would be appreciated. Marcel Veldhuizen
