ok, lets correct for aspect ratio, and add borders to the full screen version of ep 4 se...

avisynth script

----------------------------------------------------------------------------------------------------------------

# show clips in variables a,b on top of each other like this:
# a
# b

# trimmed past the crawl which didn't work properly

clip1 = Mpeg2Source("M:\data\movie\dvd\star wars ep 4 - se Fullscreen\VTS_02_1.d2v").trim(8945,0)

clip2 = Mpeg2Source("M:\data\movie\dvd\star wars ep 4 - se\VTS_02_1se.d2v").trim(8945,0)

# add borders to match horizontal size

clip1 = clip1.addborders(280, 0, 280, 0, $000000)

# resize the second clip to match aspect ratio

clip2 = clip2.crop(0, 50,0,-50).BilinearResize(1280,560)

# stack the two clips and show frame numbers

StackVertical (clip1,clip2).ReduceBy2()

ShowFrameNumber(offset=9, text_color=$ff0000)

=====================================================

and now for the really cool part..
