I have a VB.Net app that I developed following the examples in the SDK. We
are trying to encode video from a DV camcorder. If we encode at 640*480 and
deinterlace the video the encoding process does not seem to keep up with the
video playout from the camcorder. In fact it can take as much as five times
the length of the video to complete the encoding process. Using the same
profile in the Windows Media Encoder it keeps up and looks good.
Can any one explain this and help me fix the problem?

Thanks Dave

Fixed my own problem. MS sample code shows to assign source audio to the
source device.

' Add an audio source and a video source, then specify a source file.
....
Set SrcAud = SrcGrp.AddSource(WMENC_AUDIO)
Set SrcVid = SrcGrp.AddSource(WMENC_VIDEO)
SrcAud.SetInput ("Device://Device resource name")
SrcVid.SetInput ("Device://Device resource name")

WHen I remove the following line every thing keeps up.

SrcAud.SetInput ("Device://Device resource name")
