Troubleshooting a corrupted .wmv file

[JustSteve]

I'm getting reports from users who say that playback of a wmv file is interpreted by a windows dialog that 'This file is corrupt'. I can't trigger the error on my machine. Is there a utility that can deal with error conditions like this? Perhaps something that re-encodes the file without any explicit conversion?

(this is a 2 hour 100mg file so you won't want me to upload it but I suppose I could publish a link if desired)

mny thx

Are those users playing the videos on a relatively recent version of Windows, with all of their Windows Media codecs (and/or ffdshow) up-to-date? (I'm not sure whether or not Microsoft has updated the codec versions for XP and earlier to handle everything that may be implemented in a WMV, including being able to correctly interpret HD videos, and DRM.)

What player are they using? If they're not already using VLC or an mplayer variant, they might try those, too. Especially if they're not using a Windows OS. However, those may not completely support all forms of WMV (I'm not sure if support for Windows Media 3 or 9 in a WMV has improved (or by how much, since I last checked), how well players like VLC/mplayer handle HD WMVs... and none of them certainly support DRM.)

...come to think of it, the video isn't DRM-protected, is it?

If it is corrupted you can run it through asfbin and create a new wmv.
