.ASF is a retired format. I believe WMV is to replace ASF.
 
WMV is a streaming format. It means, the video started to play after the first few 
seconds are downloaded. It continues (streams) to download the rest while viewing the 
first few seconds.  After you watched the whole clip the first time, the whole video 
actually has been downloaded to your computer.
 
Depends on the web server and protocol settings, you might be able to "grab" the whole 
file to your computer. It if is from any web server sending through HTTP, after you 
view the video, assuming you are using Windows Media Player, you can use File, Save As 
to save your clip. 
 
There is an .ASX format. It is a text file (metafile) with XML content specifying the 
source of the video clip and other meta-info (author, copyright...). If for some web 
site it delivers the .asx file, you can open it to see where is the actual media file 
(.wmv or .asf) is pointing from. 
 
However, if it is deliveried by other protocol (mns://....), most likely, the media 
server will not allow you to save. You might need to use some tools to do that. Those 
tools actually fake themself as a Windows Media Player so the Windows Media Server 
will keep sending the stream. Once the fake WMP got everything, it gives u an option 
to save the media file.

Mark;

A .wmv file is (typically) a Microsoft   streaming media format found on many web 
sites.

NOTE:
Common Windows   streaming formats: 
.wmv = "Windows Media Video", 
.asf = "Advanced   Streaming Format"

The wmv file that you download is only a partial   file. This is how they keep the 
file size low.
When you click on a ..wmv   movie link, you download a partial file, and the rest of 
the file
stays on   the server of the original web site. 

When opening a .wmv file, you   usually see the "buffering" displayed in the info 
window.
That's Windows   Media Player downloading the rest of the file from the web server 
that   
originally hosted it.

There is a way to download the complete file,   using a 3rd party program like 
"X-Video Converter"
( http://www.xvideoconverter.com/   )
X-Converter automatically downloads the rest of the file, adds it to the   partial 
file that you 
have, then saves the new file as either an ..avi,   .mpg-1/2, VCD/SVCD/DVD, or 
.wmv/.asf.
X-Video Converter can also convert   standard .avi or .mpg into either .wmv or .asf 
files for web
hosting.   

X-Video Converter can also join or split video files into smaller   files.
It's a very handy program. I paid around $30.00 for the   program.
There is a downloadable "demo" that has a water mark on exported   files.
The licensed version doesn't have the water mark.

If you   saved the new file as an .avi or .mpg, you can then import the new file   
into AP for editing.

NOTE:
The resulting file is usually many   times larger than the original .wmv file.

Here's an example:

1.   I have a .wmv file that's 667Kb
2. I load the .wmv into X-Video Converter,   and select exporting the video 
    as an uncompressed .avi   (best quality)
3. The resulting video file is 87.9 Mb  (that's 132   times larger)
4. I then import the .avi into Premiere, and export the avi   using the DivX codec.
5. The new (compressed) file is now 6.2 Mb 
(much   smaller than 87.9 Mb, but not nearly as small as the original .wmv   file)

Now you can see why some people use the .wmv format.
Leaving   much of the file on their server allows the downloaded file to be much   
smaller.
