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.
Thanks in advance
