Hi,

I'm using DSPack to play a MP3. When Rate > 1, GetPosition function of
IMediaSeeking Interface get very wrong position. As much as Rate
increase GetPosition provide larger number for the same position.

It's very odd behavior for me. Can somebody describe how this
GetPosition work and why it give different number for the same
position when Rate > 1

As I see in http://msdn.microsoft.com/en-us/library/ms786010(VS.85).aspx
GetPosition is independent of the playback rate. But actually it is
NOT. I don't know this is problem of DSPack or I'm wrong in something.

I asked the same question in Progdigy forum:

But I didn't received answer.
