H264 in AVI is a hack and not officially supported.

no dont misunderstand its source is xvid in the pin info not 264

i mean 264 with coreavc works butter smooth,

but if i play a video with .avi file extension wich of course uses lav cuvid , mostly xvid or divx as source it gives me jittery playback , thats what i meant

You can always turn off xvid/divx decoding in LAV CUVID.
AVI is kind of broken by design and can cause this problem very easily.
