Unfortunately I can't play the streams.

I got the following URL with URL Snooper:
mxv://210.122.109.169/VOD1/144000/144753.wmv

changing mxv:// to http://, mms:// and rtsp:// doesn't help to record the stream.
I suggest you to try WM Recorder in the Real time recording mode (ADA or PRO). It might help.

Also try Replay Media Catcher with both audio and video streams.

Both WM Recorder and Replay Media Catcher are free to try so you can use their demo versions for free.
