Windows Media Player wont play recording

  • Problem
  • Updated 1 year ago
  • Solved
Can someone please advise:

We sent the link to the recorded webinar and a user reported the following message:
"Windows Media Player cannot play the file. A network firewall may be preventing the player from opening the file by using the UDP transport protocol. If you typed a URl in the open URL dialogue box, try using a different transport protocol (e.g. "http:").

What does this mean?

In some networks UDP and TCP is blocked by a firewall or network security which may not allow you to view the recording. Disabling the UDP and TCP protocol will allow Windows Media Player to stream the recording.

Windows 7

- Click Start
- Click All Programs
- Click on Windows Media Player
- Click Tools at the top of the menu bar
- Click on Options
- In Options window click the Network tab
- Under the section titled Protocol for MMS URLs uncheck the boxes RTSP/UDP and RTSP/TCP
- Click Apply
- Click OK

Windows XP/Vista

- Click Start
- Click Programs
- Click Accessories
- Click on Windows Media Player
- Click Tools at the top of the menu bar
- Click on Options
- In Options window click on the Network tab
- Under the section titled Protocol for MMS URLs uncheck the boxes RTSP/UDP and RTSP/TCP
- Click Apply
- Click OK
- This should now allow you to view archived webinar.

Unable to view recorded webinars - asx file fails to connect to download .wmv file. Firewall turned off. O/S Windows 7. All patches up to date. Same problem on several PCs. Tried it on Windows Media Player and Real Player (associated selected player to ASX and WMV file types). Installed g2m codec and also latest Windows 7 codec packs.

Media Player reports "Windows Media Player encountered a problem while playing the file."

Any help would be gratefully appreciated

Hi Simon, please review the information above. If this doesn't apply to you please provide some more details e.g. are you on a company or home network?

I have a similar problem.

Windows 7 Home Premium 64 bit all patches applied brand new install
Downloaded and installed the G2M codec

I have made the changes listed above
- Click Start
- Click All Programs
- Click on Windows Media Player
- Click Tools at the top of the menu bar
- Click on Options
- In Options window click the Network tab
- Under the section titled Protocol for MMS URLs uncheck the boxes RTSP/UDP and RTSP/TCP
- Click Apply
- Click OK

and have turned off the windows firewall.
This is on a home network.

Point my browers to a link that was sent to me with an ASX file.
Windows media play opens up and I get audio, no video and no errors.

Very very frustrating.
