Earlier today I was asked by a user via a Question Defense comment on how to play a WMV file that would not play by default via Windows Media Player. There are numerous tools available that will provide information about audio/video files and the codecs needed to play them but I have found that AVIcodec works really well in most situations. Below is information on how to install AVIcodec and how to analyze video files once AVIcodec is installed.

How To Convert .WRF Files To .WMV, AVI, MP4, XVID, or MPEG

Insights66 Comments

Someone sent me a WebEx webcast they wanted me to view this afternoon. The file had a .WRF file ending which stands for WebEx Recording Format which is one of the two file formats that WebEx webcasts are saved as. The other format that WebEx files are saved as is the ARF or WebEx Advanced Recording Format. Typically you could simply download the WebEx Player available by clicking here however you may want to convert this video, which requires the WebEx Recording Editor, to provide to others in a format they can view without having to install an application. It took me awhile to figure out how to convert this file properly since I only seemed to be able to find the older WebEx Editor versions. I finally signed up for a trial account and was able to download version 3 of the WebEx Recording Editor which allowed me to convert to WMV format and from that I was able to convert to any other video format including AVI, MP4, XVID, and MPEG. Follow the directions below to first convert the .WRF to .WMV and then the second set of directions if you want to convert to another video format.

Roxio 2010: The File You Are Trying To Use Cannot Be Edited, And Has Not Been Added

Insights6 Comments

When using Roxio Creator Premier 2010 to encode a video to DVD format and burn to disc I received an error. I have been burning AVI, MPEG, MP4, Quicktime, and other video formats using this version of Roxio Creator 2010 for some time so I was surprised to receive an error. Initially I thought that the error was caused by file permissions on the file because a friend had provided it to burn and this was the only initial difference that I could find with the video versus other videos that I had burned. Below I describe how to troubleshoot this error and what I eventually did to resolve and move past this error. In the end I was able to burn this video using Roxio Creator 2010.
