Picture is jumping in AVI_IO

[Joxx]

After capturing YUY2 i AVI_IO the picture starts jumping about 10 pixels with a tempo of aprox. 5 jumps/s. This stops when drivers are reloaded (device menu). Also in VirtualDub the picture is jumping, but only when capture is in progress.

I have a marvel G400 and I use VT 1.52, how do I stop this?
