Avisynth problem

[sigma_sigma]

I use avisynth 2.5.5.and I have this little script:

AVISource("c:\bb.avi")
Levels(0, 1, 255, 0, 255)
AddBorders(0, 92, 0, 92)

When I open the avs file with virtualdub The last few seconds of the movie dissapear.why?
If I try to encode into nsv format with nsvtools(nsvenc) it is returned a big memory error "The instruction at"0x00e68bfc"referenced memory at"0x00e93608" .I specify if I'm trying to encode with virtual dub or with nsv the avi file works fine..avisynth is the problem.
I don't know if this is a right place to ask this, if it is not, I aplologyse...
Thanks in advance!

Try latest v2.5.6. Could you upload a sample avi somewhere?

I don't know where can I upload a 15 Mb file. So u can download directly from my computer (I have a web server installed) download (http://sigma.opalid.ro:6127/Sample/avi.avi).
Thanks

Yes, i see. That's weird. Frame 910 is just duplicated 176 times till the end of the stream. Video is XviD. I will submit a bug report to sourceforge.

avi can be downloaded here: http://rapidshare.de/files/3969518/sigma.avi.html

edit: perhaps there's something wrong with the avi. If i set VDub on 'Direct stream copy' and encode the resulting avi, the encoding is fine.

Seems like the avi file is crashed somehow. Can you tell me how can I edit the avi file to see frame details like in your post"Frame 910 is just duplicated 176 times till the end of the stream"?...I mean with what soft can I do that? I've seen in virtual dub an option about test video stream..
It is stranged because the avi file is cuted by me with virtualdubmp3, because the original movie sound is vbr, and if I use virtualdub, the sound is desync.
So I used virtualdub mp3 , I selected a little movie segment, direct stream copy video and audio and save the avi.avi file...
I don't understand why virtual dub mp3 freeze didn't do his job corectly...
Thanks very much !
