I have not looked at this is some time, but with some deinterlacers I 
worked on,  the timestamps were messed up coming out of the deinterlacer 
and I added code to copy the original timestamps onto the deinterlaced 
frames, and interpolate the time stamps for the extra frames created. I 
am not sure which deinterlacers had the problem, I think maybe the 
NVIDIA Shield built in deinterlace was like this.
