OK that's a good first step.
However there are several more places where this can break down.
... If you're referencing your content using an ASX playlist on the
client side, and the playlist has an entry with the element
<entry clientSkip="no" />
... If the server side is running this content from a playlist, and
the element for the media you're playing has the noSkip attribute set
<media noSkip="true" />
... then your viewer won't be able to seek or skip past the content
until it's played
If your problem is specifically frame level access, WMP doesn't
guarantee you can pause on a particular frame. This can be affected by
keyframe spacing and content type (though from WMS the only content
type usefully available is ASF / WMV, so it should work).
You may also have embedded the player without using
player.settings.setMode("showFrame", true);
In addition, your description of stream content moving to the
beginning (and presumably, stopping playback) sounds like your
javascript is returning boolean "true".
Depending on how the page is authored (eg by using an <a
href="javascript:" /> link) , this could be forcing a page unload and
of course restarting the player when it does so, if it's set to
autoPlay.
You can check using client side script if the player is able to do the
Step feature, by querying
player.settings.isAvailable("setMode");
then you can check if the actual step command is available with
player.controls.isAvailable("step");

Re: controls.step does not work !
Thanks Neil,
for all the details !
I've two different needs, so I use the mms:// for a single file to
select the segment, then I create a ASX file to show the segments in
sequence.
Is not a problem about skip/noskip...
I've done some more test, using different configuration in the
media encoder, but I was not able to generate a content with frame
access available.
In all my tests the setMode settings is available, but the 'step'
feature no....
Do you known where I can get a .wme (windows media encoder session
file) example to try to understand what's is missing ?

Re: controls.step does not work !
I don't think the session file will help much other than to provide
the keyframe rate of the encoded file. You can just save the pfoeil
though - which is the encoding settings without hardware / file source
information.
In WM Encoder, open your profile (skipping the Wizard interface),
click the properties button, then Compression tab, and click the Edit
button.
From there, click Export... which will save the compression profile
settings as a .prx file : You would normally see some of the
predefined ones listed at that point, which should be installed in the
WMEncoder/Profiles directory wherever WME has been installed.
Alternatively, you can save the whole session from WME as a .wme file
type, by going to the usual File -> Save As dialog from the encoder
menu
If you need to actually inspect a previously encoded file to see where
the keyframes sit, and where the I (intermediate) / B (backward)
frames are, install and run Sliq WMSnoop and drag the WMV file onto
the snoop tool : http://www.sliq.com/default.asp?view=wmsnoop

Re: controls.step does not work !
Hi !
first: I found a bug in my javascript... after using the step()
function I was setting the player.controls.currentPosition to a wrong
pos... I remove it...
second: using the mms:// protocol the step is never available (for
me...), but if I use the http:// protocol step() is available and
works correctly... same file
mms://MyTest/file1.wmv does not work
http://localhost/MyTest/file1.wmv IT WORKS...
I'd like to understand better this behaviour...

Re: controls.step does not work !
Vary the file from your HTTP server (e.g. by adding a query string) or
delete the browser cache every time you load the page (or, set the web
server to expireByType for WMV files immediately).
It's probably playing back from the local hard drive, where you should
always be able to use step(), rather than from the web server - the
steps above would isolate that case.
Alternatively, if you pull up player advanced statistics, you'd be
able to see Protocol:CACHE rather than Protocol:HTTP
