DVRMStoWMVHD - ATSC / AC3 DVR-MS Conversion

DVRMStoWMVHD.exe is a command line utility that converts dvr-ms files to WMV files.  It is designed to work with ATSC files with HD video and AC3 audio streams.  By default (no custom profile is specified) to will convert the dvr-ms file to a WMV file with VC-1 video and WMA Pro 5.1 audio with a programmatically built profile based on the attributes of the source file.  A custom profile can be passed as the third argument if more control is desired over the target format.  I have tested the cbrZune.prx file that comes with DTB, and it will convert files to that format, including downmixing the audio, but the video will skew a bit because of aspect ratio changes.

AC3Filter is preferred, and needs to be configured to deliver 5.1 audio for AC3 streams for this to work properly.  Other AC3 decoders should work if properly configured, but will not be supported. 

While the application should work on XP if WMF11 is installed, it was developed and tested on Vista. 

syntax:

"in.dvr-ms" "out.wmv" ["wmv.prx"] 

known issues:

  • the output file is not indexed
  • meta data is not copied from the dvr-ms file to the wmv file
The application is currently only available to Early Access members, it can be download here.

Forgot to say that this is very, very beta.

UPDATE: Fixed indexing issue

UPDATE2: Added metadata migration

Das Kommandozeilen Media Center Tool DVRMStoWMVHD erlaubt die Konvertierung einer DVR-MS Aufzeichnung in das WMV-HD Format. Man erhält damit konkret ein VC-1 Video samt WMA Pro 5.1 Audio wenn man keine Änderungen an den Standardeinstellungen vornimmt
