Just a heads p about my experience, don't know if it is only my mahcine acting up or a problem with cabopus dv coded and win 7 64. I installed canopus dv codec right from videohelp in the tools section and tried to put my video into vdub and still failed not knowing fourcc DVSD. I googlesd a bit and installed a panasonic dv codec I found and so far it is working fine.
If anyone has info on this, is it normal or something weird with my particular machine, I'd like to know. It might be a good idea too if someone would update the dv>tools section to include some more dv codecs maybe to, the canopus is currently the only one linked from here.

I'd be extremely surprised if either one of those codecs would work with Win7v64. Those 2 codecs were last update in the '90s! Win7 didn't exist. Neither did 64bit PCs. Why would you expect them to be that forward compatible? You just lucked out with the Panny codec (though I wouldn't use it - color doesn't encode/decode correctly).
You could try the Cedocida codec, but even that isn't officially rated to be totally compatible with Win7v64 (though it is still updated).
Also, remember that you have to use 32 with 32 and 64 with 64, not mix and match. So make sure your 32bit codec is using 32bit Vdub, etc.
BTW, do a tool search on "Codecs" or "DV codecs", not "DV tools"...
64 bit programs require 64 bit codecs, 32 bit programs require 32 bit codecs. Some 32 bit codecs need a special install procedure in Win64:
Cedocida has both 32 bit and 64 DV codecs. VirtualDub (32 bit and 64 bit) has a built in DV decoder, try using it.
Hmm. A coplre reaons why I tried what I did. When the fourcc dvsd was unrecognized I used directshow, but it messed up and made a 30 minute file into 8 hours for some reason. Then I just googles searched for vfw dv codec, which brought me here to the dv section where there was a dv codec posted, as I said did not work. For the record I am using 32 bit vdub, 32 bit avisynth.
As for vdubs built in codec, that is strange becasue actually the other day i decoded the same kind of file fine without having installed it, but then the next day they stopped working. maybe I should try to reinstall vdub? I did think it was odd and I was annoyed that it worked on day and then not the next.
You may also have some conflict with your fourcc assignments. Make sure to remove those others first, then add Cedocida (which should overwrite good assignment values).
Note: the Canopus codec was designed to primarily NOT use the standard dvsd, rather their own cdvd or cdvc so that some other codec wouldn't be trying to usurp the decoding (and do it wrong). If you have tried some canopus encodes and later have trouble, it could mean you just need to change the fourcc to dvsd so that Cedocida (or MS's directshow decoder) will work.
