need help with using avisynth for playback

[saint-francis]

When I try this script I get errors in involving anything below the video source:

video = DGDecode_mpeg2source("G:\my movie",info=3)
ColorMatrix(hints=true)
crop( 0, 58, 0, -64)
Spline36Resize(720,304)
Undot ()
audio = DirectShowSource("G:\my movie.mp4", audio=true)
AudioDub(video, audio)

I tried making a script for just the video and importing it and using that as the video source and then I get errors involving audiodub. But if I don't filter the video at all it plays fine, albeit unfiltered.
Here's an example:

video = DGDecode_mpeg2source("G:\my movie",info=3)
audio = DirectShowSource("G:\my movie.mp4")
AudioDub(video, audio)

Can someone please explain to me how to correctly use audiodub? Or is there a better way to accomplish what I'm trying to do?

Try this:

DGDecode_mpeg2source("G:\my movie",info=3)
ColorMatrix(hints=true)
crop( 0, 58, 0, -64)
Spline36Resize(720,304)
video=Undot()
audio = DirectShowSource("G:\my movie.mp4", audio=true)
AudioDub(video, audio)

Study the Avisynth syntax, especially the implicit variable 'last'.

Thanks Neuron2. It worked like a charm. I have found the section of the avisynth wiki explaining block statements and am studying it.

New issue along the same line.
Why isn't this script working? It works fine in AVSP but MPC doesn't want to deal with the audio.

DGDecode_mpeg2source("D:\FLETCH\VIDEO_TS\VTS_01_1.d2v",info=3)
ColorMatrix(hints=true)
crop( 0, 8, 0, -12)
LanczosResize(720,400)
video=Undot ()
Audio=DirectShowSource("D:\FLETCH\VIDEO_TS\main.mp4",audio=true)
AudioDub(video,audio)
