DGBob causes back-forward motion

[falconfighter]

LoadPlugin("D:\Program Files\AviSynth 2.5\plugins\mpeg2dec3dg.dll")
LoadPlugin("C:\avisynth plugs\avisynth_c.dll")
LoadPlugin("C:\avisynth plugs\DGBob.dll")
LoadCPlugin("C:\avisynth plugs\smartdecimate.dll")
MPEG2Source("C:\1x05\1x05.d2v")
SmartDecimate(tel=.25, bob=DGBob(order=0, thresh=20))
produces a back-and forward motion of about ~2 seconds - video will play from start for 2 seconds - then move forward about 3 seconds - then move back again.
A 1 min sample is here - sorry about the quality. This is an apache server off my computer - you have until 9:30 tonight to get it. Be nice to my bandwidth.
edit: AACK! just looked at it. the video quality sucks. any pixellation is caused by me doing a 256k/sec xvid compression. Any jumping is my filter.
EDIT: Problem solved. saving my bandwidth.

Hi there.

There are a few probs that need workarounds for SmartDecimate (nothing hard!)

You need to put DGBob (or any 'bobber') outside the SmartDecimate function, like this:

assumeBFF() # just to make sure that SmartDecimate knows
a=DGBob(order=0,thresh=20)
smartdecimate(tel=0.25,bob=a)

Replace your current SmartDecimate line in your script with the above and it should solve your problem - if not then check the field order is correct.

Another thing is that I have sometimes experienced crashes if SmartDecimate.dll is in the autoloading plugins directory, so keep it elsewhere (which you already seem to be doing so no probs here)
