ie this error:
running it thru asfbin app fixes it ( http://www.radioactivepages.com/asfbin.aspx ), but i have lots of such files so it would be easier if one could load them straight to vdub...
here's a sample file if you need it

Although the ASF specification allows a replicated data length of zero, it is so rare that in all these years I have never seen it. The error thrown by the code is kind of like a mountweazel, in that I put it there just to alert ME if ever such a thing was found.
Congratulations Ivo, you are the first to have found it. 
I was not able to download your sample, so I am going to have to assume that there is not something else seriously wrong with those WMVs you have. Anyway here is a new build which removes the error:

i've found TON of it!
here
http://www.slobodanpraljak.com/ratni_video.html
(it's war stuff, there might be some gore there....but dvd20, dvd24, dvd30 are safe for anybody's eyes...i just inspected them in vdub, so yes, the fix works...you can dload them via "pokreni" mms link)
as far as i see most files have this error. only smallest don't.
(for example i think i picked DVD-27 (wmr).wmv (3.43mb) for upload, but then saw it loaded ok, and then picked the next bigger file that had it.)
also, this was ripped with some mass dloader (my friend was doing that...i think it was wmrecorder
http://www.wmrecorder.com/ ) dunno if that messed itup...
loaded it to hex editor and don't see what was the encoder...

heh, so rare?
interesting.
thanks a lot for the quick fix!
i need this because vdub is much better way to quickly inspect these files than usual video players...better timeline resolution.
this fix makes that task a lot easier...

I have 2 samples that come from a camera.
With the previous version of the input plugin they get replicated data length of zero,
instead with the new version:
The 40MB file after direct strem copy show garbage in the video and audio is present but it cannot be played;
The 65MB file cannot be opened, it say "File ... does not have a video stream.".

To update, I have found the problem and fixed it. I was not correctly handling the unusual case of replicated data length zero.
I am currently trying (again) to fix audio/video sync issues which have plagued this plugin since the beginning, therefore I would prefer to delay the next release. But if you have an urgent need for the replicated data bug fix, just let me know.

Well, again I've given up on trying to fix the audio/video sync issues, after much frustration. I do still believe it is possible to fix, but it pretty much involves me writing a dedicated Windows Media Audio decoder into the plugin! I am totally going to have to defer that for some later time (if ever).
Anyway, version 2.7 has the aforementioned fix for replicated data length zero:

Test file (Afo4 - Stupido v2.wmv): http://uploading.com/files/1m439f9d/Afo4%2...upido%2Bv2.wmv/ (click on "WAIT TO DOWNLOAD")
In file informations with version 2.6 it say "Length (duration): 6912000 samples (3:36)"
instead with version 2.7 it say "Length (duration): 6909918 samples (3:36)".
Is it a new bug or it was wrong in the previous version?

The crash was due to an incorrect nBlockAlign value in the WAVEFORMATEX structure of the audio stream, and that was a side effect of some changes I made while trying (unsuccessfully) to fix the audio/video sync problem. The crash is fixed now:
http://fcchandler.home.comcast.net/Plugins/WMV
Regarding the number of WMA samples, there is some guesswork involved to estimate that number. It isn't going to be 100% accurate. However, I believe the latest version delivers a more accurate guess.
