C# DirectShow Player that works with AVerTV PCI-E HD Capture Card

Hi, We are using the AverTV PCI-E HD Capture Card to display video in our application. We can capture the video and display it on screen, however the video seems to get out of sync and become jerky or stuttery as time goes on. We know it's not a hardware problem as the card works correctly in it's own supplied software. We also want to be able to apply a filter so we can DeInterlace the video feed. Ideally we would want this to work with any video capture card / webcam that we use. Requirements: To create a video player that: 1) Is based on the [login to view URL] Library or can be used via C# 2) Allows selection of Video Capture Devices 3) Allows selection of Input Resolution of Capture Device 4) Plays the video in a frameless window that can appear above all other windows on the desktop and can be resized and positioned via C# 5) Plays the video smoothly... no jerkiness or stuttering (1280x720 @ 50 Frames) 6) Can have a filter applied to it such as FDShow or other to allow DeInterlacing 7) To play audio if the device supports it... but this is less of a priority. We have our own player at the moment so we know that most of these options are fairly easy to achieve as the well known "PlayCap" sample does just about all of this. The priority is to make the video smooth and to be able to apply a DeInterlace filter.
