After posting my question, I notice that the code I was referring to is not showing up in the post.  Apparently, if you use the "greater than - less than" brackets that are in the code, the text does not show up.  So I have removed them in the code below.  Here are the portions of the web.config code that get modified to support the DNNMasters MPUS-Xtreme module:

Since your last posting, we have still not resolved this UVG issue.

To answer your questions: Yes - The "different skin" we metioned does have a black skin at the bottom and a large light gray play button in the center of the video player.  We did check the Event Viewer for any logs that may relate to this issue of the video not playing, but have seen no log files that pertain specifically to the videos not playing.

As far as invoking the vid.aspx player, we did use the link you sent "http(s)://yourdomain.com/desktopmodules/ultravideogallery/vid.aspx?vId=your video id." and what displayed on the page was simply the xml information about t he video.

Herer is a list of other troubleshooting that we attepmted:

- Tried to change the ashx setting in IIS to NOT verify files exists - failed
- Tried to change the HTTP header section in IIS - failed
- Tried to add/delete MIME type (.flv) - failed

- Tried running the video admin configuration wizard several times
---- Suggestions were:
-------- Select 'I can't see it'
-------- Select 'I can see it'
Both failed

- Pored through forums with no luck
- Searched internet through google with no luck
- Looked for specific issues relating to Internet explorer - failed
- Tried playing the 'FirstRun.flv' - failed
- Tried accessing videos directly via URL - failed


However, we did notice that the videos will play with http and https when our site is viewed through Firefox (version 2.0.0.16).

Your help and suggestions are most appreciated.

1. I wish I had a domain to give you so that you could actually see this issue in action, but this website does not yet exist at a publicly accessible address.  It is on a development server that exist only within our network.

2. As far as the UVG version that we are using it's 2.4.2.  The first post will list all other UVG module versions as well as the MPUS module version.  We went to Snowcovered.com, where we purchased this module originally, to get the newest version of UVG.  However, we did not see the UVG 2.4.4 listed there.  We did download the 2.4.4 trial version on the bizmodules site and installed it onto our website, but it did not correct the problem.

3. Yes, we did test to confirm that when we remove the MPUS entries from the web.config file the UVG Video Player will play videos correctly using both http and https.

You mentioned that you have another client that is also having the same issues with MPUS and UVG.  Does this mean you are already attempting to implement some kind of code fix for this?

Thank you for your prompt responses and assistance with this matter.

No answers as of yet, but another user has posted this same problem on the DNN Masters site.  I thought I would post the link to the thread on the DNNMasters forum where this issue is being discussed for further reference:
