How to convert Webex’ WRF to any other video format

Note that in an announcement on the Philips forums about being able to record they mentioned:

Saved Recordings will be encrypted and can only be decrypted with the same TV, so sharing movies will NOT be possible.

No.

Handbrake can only convert video using these codecs:

• FFmpeg's MPEG-4 visual codec
• x264
• XviD (support for this was dropped with 0.9.4*)

… and as a container** only supports:

• MKV
• MP4
• AVI (support for this was dropped with 0.9.4, especially since the AVI container is lacking so many features)

There aren't that many encoders for Windows Media Video out there. FFmpeg itself only supports encoding of WMV 7 and 8, not version 9. In your situation, I'm sure MP4 containers are properly handled by most playback software. The same goes for MKV, which is seeing more and more support these days.
