Status: RESOLVED INVALID

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

In the link to a playlist at
http://69.1.135.85:8081/audio/29june2005/29june2005.m3u FireFox (& Mozilla)
calls Windows Media Player (v10), BUT WMP claims it cannot open the file.
Clicking the same link in Microsoft IE 6 calls WMP and it begins playing the
.mp3s. Reproducable on 2 XP Home computers. Tried from 2 locations (one local
network sitting next to the server, one from across town).

Reproducible: Always

Steps to Reproduce:
1.Go to http://69.1.135.85:8081/audio
2.Click the first link, which goes to
http://69.1.135.85:8081/audio/29june2005/29june2005.m3u
3. See WMP start and then give error dialog box.

Actual Results:  
Windows Media Player starts, then gives an error dialog box:

"Windows Media Player cannot play the file. If the file is on another computer,
verify that you are connected to the network. If you typed a path, verify that
it is correct. If the problem persists, the server might not be available."

Expected Results:  
Play the playlist

The file is a recording of an in-house lecture last wednesday, so it is not a
copy protection issue. WMP claims it is a network problem. There is no proxie
server: in one case the server is literally on the same hub/switch as the
client. Server is running the current version of Apache. My gut feeling is that
some parameter is not being passed correctly, such as the file name. I re-named
all files involved and edited the playlist (text file) to remove all embedded
blanks. Still no help.

I use Winamp to handle *.mru files (Content-Type audio/x-mpegurl send this
server) and it works.

I could not cut/paste the info from the dialog box, so I posted two screen cuts
on my web. Check jdnash.org, the nav bar on the left, at the bottom.

This is a known bug in the NPAPI WMP plugin.  IE uses a different WMP plugin (the ActiveX one, to be exact) than mozilla, which is why it works in IE.
