Unfortunately I dont have any Windows PC available right now to test this problem out by myself. Obviously a codec was used to encode the video on your PC that is not present on your husbands PC - so I will give you general recommendations on this:
To playback the file try downloading one of the all in one media players - especially the VLC media player which has a lot of codecs built into it.
Alternatively, again to play it back, you could try downloading a codec pack. Try Vista Codec Pack or K-Lite Codec Pack.
Let me know if this was helpful, if not let me know and I will try and come up with more suggestions.
I made a Windows Live Movie Maker slide show on my Windows 7 computer before it crashed. Thankfully I had saved the movie to removable storage. Now, I am trying to play the movie on my husband’s computer, but it is vista and has WMM on it. It says I need to download a codec for it. Is it going to be possible to restore this movie on this older computer? I have to have this by Friday!!
Thanks for any help you can give me!!!!
