Dear all, When I use PowerDVD/WinDVD SPDIF pass through and select direct sound audio render, I always get a lot of zero data with a few valid data in the beginning of playback. Due to use driver to decode the AC3/DTS data, I am not sure how to handle these zero data. Any suggestion? (Treat them as data need to be decoded or as rubbish and discarded) BTW, if I select waveout audio render, All the data at the beginning are useful valid data,which I can decode.
