Canopus ADVC-100 Capture Yields AVI with incorrect codec (DVSoft)?

I capture my video using Vegas 5.0 with the ADVC-100 connected through a firewire card in my computer. My understanding is that the ADVC-100 compresses the video in Canopus DV and passes it off to the PC for storage in the AVI file. This file's compreesion in Windows Explorer's Properties is "DVSoft" not "Canopus DV" or even "MS DV". I have Procoder 2.0 on my PC so the Canopus DV codec is installed. VirtualDUB lists the file's compression as "DVSoft" also. Using the utility AVICodec, the video codec of the ADVC-100 captured AVI file is "dvsd (Stub DV Compression Manager) = Sony Digital Video".

I have always wondered how Vegas would know to mark a captured AVI file as "Canopus DV" when it doesn't know that a Canopus ADVC is doing the compression.

This whole thing came up when AVISynth's Info command said that my captured AVI had a "RGB32" colorspace when Canopus DV files have a YUY2 colorspace.

Any ideas why "DVSoft" is marked as the file's compression and/or how to correct this problem? I tried uninstallinj the DVSoft codec but it keeps coming back .Thanks...

You are right. The ADVC compresses the video by using a Canopus hardware dv codec. But it's the capture application which determines the header to be used in the AVI file written then. So if you use Vegas for capturing then Vegas writes the header. And because applications other then Vegas cannot use the Sony Pictures DV codec they will take the latest VfW DV codec which was installed on your system to decode the file.

So everything is alright on your system.
