How to record specific segments of a long Windows Media Player streaming

Hello,
New to the application but technical on the computer. I have a very long (2 hour) Windows Media Player streaming from an URL that I only want to record certain segments.

For example, I want to record 16:00 mins in until 16:45. Then I want to record 32:10 minutes in until 32:55.

How do you (if you can) use the Replay AV to do this. It starts at the front (00:00) and wants to record the whole thing and 2 hours would take forever.

I also notice the Vendor has (what looks like a screen capture application and would that be better suited for what I want?

Thanks in advance,

Bob
