PROBLEM: 
Regardless of which computer I use , Mythbox (localhost) or Win7 PC (on home based LAN), no movie plays.


DESCRIPTION:
I'm trying to stream video/movies to my webbrowser (ie:Firefox, Chrome, Opera, IE). I've created these movies using Handbrake 0.9.9 rev0 and have "web optimized" m4v files. These movies play fine using MythTV's UPNP (media server), and via MythBox's Samba server (Network Shares), but I can't get them to play/stream using a webbrowser.

When I access Mythweb via the webbrowser, it appears normal. I see the webpages served up and the video list appears with all of the coverart visible. I should also note that for the purposes of testing, I've disabled the login authentication code that appears in /etc/apache2/sites-available/mythweb.conf.
In addition for testing purposes, I selected a movie that is an .mp4 format rather than .m4v only b/c I noticed that the php script /usr/share/mythtv/mythweb/modules/video/stream.php explicitly supports mp4 and not m4v.

So when I use the Mythbox's Webbrowsers (a.k.a localhost) to click on a movie, here are the headers recorded....

The first thing I noticed is that the "Content-Type:" is misspelled. So I edited the php script /usr/share/mythtv/mythweb/modules/video/stream.php so that this typo was fixed. But after I fixed the typo, I noticed that the header response was still wrong. It is wrong, b/c the code with the script should have identitied the mp4 file type and served up the Content-Type: video/mp4 and not Content-Type: application/octet-stream. Again, the code within the script specifies this but the output did not match.

After another review of the code within the php script /usr/share/mythtv/mythweb/modules/video/stream.php I changed one line:
FROM:     switch (substr($fname, strrpos($fname, '.'))) {
TO:     switch (substr($fname, strrpos($fname, '.')+1)) {

After restarting the apache server (/etc/init.d/apache2 restart), now the header for mp4 file types was correct:
Content-Type: video/mp4 and not the original mispelled header Content-Type: applicatoin/octet-stream.

But now after these changes to the php script, the webbrowsers are producing "File Not Found" errors. For some reason the URL served up by Mythweb http://localhost/mythweb/video/stream?Id=1 can't be read and the browsers hang or produce an error message.


Does anyone know how to proceed so that I can get a movie to stream?
Why isn't Mythweb sending the movie to the webbrowser? 
What link is missing between URL (http://localhost/mythweb/video/stream?Id=1) and actual movie full pathname?
