Hi,<br/><br/>When encoding MPEG-2 files into WMV using the Expression program, the file gets indexed first. This takes about 1-2 minutes. When encoding the same file using the SDK, the encoding starts without indexing step and results often in an error or wrong file duration. I cannot find the function in the SDK to index the MPEG-2 file first. Anyone know this?<br/><br/>Thanx, Joost© 2009 Microsoft Corporation.

I'll enter a suggestion into our database for a future version.<br/>Regards<br/>Dean.Tue, 23 Jun 2009 20:07:19 Z2009-06-23T20:07:19Z
