question about microsoft directshow mpeg-2 demultiplexer filter

[yshen4]

Hi, does anyone familiar with microsoft directshow mpeg-2 demultiplexer(come with directX 8 sdk)?
I have difficulties while trying to provide input stream to this filter. As
the sdk document said, this filter provide a IPIN interface (but not
IMemInputPin), so how can I feed streams received from network into this
filter? (If it can provide IMemInputPin, then the data can be feeded in with
the IMemInputPin::Receive method)
Thanks much!
