If you start playing this video with Windows Media Player and move the slider to 36 minutes you'll see that the player stops at this point and reports a "Server busy" error meaning the server shut down the connection
with a 504 error. It is probably the remote server that does not allow to play the video after this time (maybe something was going on in the show, bad language, etc).

Use WM Recorder Timed Recording options under Saved URLs and set the start time at 37 minutes. The recording will be OK up to the end. Then you can merge the two recordings in one file.
