They use Adobe Flash Player so the first software I tried to record the stream was Replay Media Catcher. It appeared to be an MP3 audio stream:
and Replay Media Catcher saved it to harddisk without any problem.

Usually I start recording from searching for the URL. Because Replay Media Catcher and
WM Recorder can cover more than 90% of the most popular media streams I run them both. Both programs are shareware, but you may use them for free to get stream URLs.

You may also use a URL Finder. It can be a URL finder that is built-in into the stream recorder like Replay A/V or you may use freeware URL Snooper.

To record any media stream:
1. Run a URL finder.
2. Play your stream.
3. Find the URL
3. Record with a stream recorder (note that stream recording software like Replay Media Catcher and
WM Recorder can automatically record streamable content).

Returning to neighbourhoodmechanic.ca. I wasn't able to find the stream URL with Project URL Snooper, WM Recorder and Replay A/V. I'll do some research to know why.
