When you use an MPEG file as a source and you have ULead MediaStudio Pro software installed on your computer, you may receive the following error message:
One or more codecs required to open this media could not be found. (0xC00D1B83)
When you install the ULead software after you install the Encoder, the ULead software takes "ownership" of some of the Encoder decompression codecs. The Encoder is then unable to decode the MPEG files properly.
To resolve this problem, uninstall (remove) the MediaStudio Pro software.
This problem occurs when you use Microsoft Windows Media Encoder version 7.0 and ULead MediaStudio Pro version 6.0.
