I have a 30 minutes wmv concert, out of which I wanted to get a 7 minute song. The problem I'm having is that all of the softwares I have tried until now don't just chop off the unwanted minutes, they seem to want to reencode the file altogether.
My file is 37,5 Mb and, with the reencoding, even when chosing divX 5.0, the resulting file is larger than my full original (even though I choose the same width, height and frame rate).
Is there any program that just removes the bits I don't want to, without forcing me to choose formats?
- Size: 37,5 Mb
Length: 30:11 minutes
Width: 320 px
Height: 240 px
Bit Rate: 177 Kbps
Audio Sample Size: 16 bit
Channels: 1 (mono)
Audio Sample Rate: 16 kHz
Data Rate: 152 Kbps
Video Sample Size: 24 bit
Stream Name: video 2
Thanks in advance!

I'm trying to cut a .wmv of a stream downloaded from play.svt.se (a swedish tv channel)
However, asfbin keeps crashing during the cutting. I've tried both the GUI version (1.5) and the command line version (1.6). In the GUI version, I can load the file and choose a segment using the sliders, but get a crash when cutting. When using the command line version, and adding the -rkf parameter, I get the error BiggerJim mentions: "Decompression error: VCM decoding driver is not available". However, after I've installed wmv9VCMsetup.exe i still get the same error message.
Here's an example of such a wmv stream :
Can someone help me find a way to cut files like that?
Do I perhaps have to do something else apart from just installing wmv9VCMsetup.exe (for example, do I have manually copy some of its files to the asfbin folder?)
I appreciate all help I can get!
this is what gspot says about the file:

I did some more testing...
If I save the stream with SDP ( http://sdp.ppona.com/ ) asfbin can cut it. But SDP has no support for multiple stream downloading so a 1 hour stream takes 1 hour to download. In comparison, some download managers support multiple thread MMS downloading which is much faster. NetTransport (NetXfer) and ReGet are two examples. But files saved with both these applications crash asfbin. (The gspot data above is from the file that NetTransport saves.)
So maybe I should expand my question:
I'm looking for a multiple thread MMS downloader that outputs files that asfbin can handle. Or alternatively, some other asf cutter/joiner tool that supports the file that NetTransport or ReGet or some similar tool outputs.
I'd prefer if there was some way to get the files from NetTransport to be handled by asfbin. Is there perhaps some tool that can "clean up" the file before inputting it to asfbin?
IMO of the situation, the problem is the source, it is encrpted or compressed for storage on the server, capturing the live realtime stream gives you the full correct stream, downloading/leeching the stream gives you the compacted stream, which cannot be edited
Well when I playback files saved through realtime and files saved through multiple threads I see no quality difference. So I think it's the "same" stream. The problem seems rather to be that it is incorrectly assembled in some way by NetTransport.
But I've found a solution now. I tried with some other download managers today and Flashget (
http://www.amazesoft.com/index_en.htm ) supports both 10 threaded downloads over MMS and outputs files AsfBin can handle (no VCM decoding drivers are needed).
So, problem solved! (by myself )
Try renaming from "whatever.asf" to "whatever.wmv".
Every "naturally-born" .wmv is in fact a .asf file.
