Error when loading .WMV files in DVD Maker

[EWG]

A month ago DVD Maker would burn a .wmv file no problem. Now whenever I try and load up any type of file (other than .jpg for some reason) I get the following error:

"The file <name>.wmv is not a supported file type and it cannot be imported"

This issue (along with several others, listed here: http://www.sevenforums.com/windows-...pdate-sfc-scannow-checksur-logs-included.html) have popped up after performing a Windows Update back on 3/14/2013.

I have taken the following actions to attempt to resolve the issue:
1. Ran a virus scan using avast! (no issues found)
2. Ran a system scan using Malwarebytes (no issues found)
3. Ran a System Repair using chkdsk /r
4. Ran a System Check using sfc /scannow (no integrity violations found)
5. Ran a CheckSUR (no problems found)
6. Confirmed that DVD Maker has no filters installed

Any help would be greatly appreciated. I'm using Windows 7, 64bit

Thanks,
EWG

I would reinstall DVD Maker and see if that repairs the damage, wondering if a common .dll it uses, was replaced by something else.
