To remove DRM (Digital Rights Management) features from a WMV file, you will need an application that plays the WMV file and re-records it in another format.
You will need to be connected to the Internet to retrieve a valid DRM license during the conversion, but after that you will be able to play the videos on the train.
Removing DRM from WMV with DRMDBG and DRM2WMV
DRMDBG and DRM2WMV can be used together to remove DRM from WMV. DRMDBG retrieves the KID and the seed from memory when a DRM protected file is being played and saves them into a key file. DRM2WMV uses that key file to replay the WMV and create and unprotected version of the WMV file.
