MacroVision question

[trolltuning]

I have an avi that I captured from a VHS NTSC tape I purchased that I'm trying to convert to DVD.
Both Virtual Dub and CCE can read the capture but any avs made with it as source has a green box.
If I recapture the video after changing to an earlier video driver that doesn't recognize MacroVision would I then be able to process with AviSynth or would the MacroVision still be present

that sounds like more a decoding problem than a macrovision one.

What are you using to load the captured file with avs?
avisource()
directshowsource()
another one?

AviSource
In that case I'll try one of the others and also see if I accidently captured in a compressed format and need to install a codec.

[trolltuning]

You were exactly right using DirectShowSource() solved the problem.
:)
Gee I thought the rule was use AviSource() for AVI and DirectShowSource for everything else but I guess there's a little more to it.

Two explanations:

- Or you are missing a proper vfw decoder, and you have a directshow one, meaning you can decoder with directshowsource,
- Or there is a bug with avs not handling correctly the vfw decoder and failing to use it while vdub or directshow can use it.

Basically, avisource will use the vfw decoder, and fails if there is none available for the given codec, it will opens only avifile...
DirectshowSource() will tries to open any media content openable with direct show...

In case any one else runs into this:
Solution 1(not good) I went into options in AviScript and changed AviSource to DirectShowSource. Unfortunately DirectShow is too slow to make this viable for making cuts.

Solution 2 (good) I downloaded a Huffy codec (I naively thought that because I had VirtualDubMod set to uncompressed for capture that I didn'yt need one). Now everything is working right.

I was wrong, installing the codec didn't help. It turned out I needed to make one of the registry changes exlained in the YV12 FAQ.
