To change your recordings directory:
1. Click "Settings"
2. In the "WMR Options" window on the "General" tab click the "Recordings Folder" button.
3. Select the directory (you can also create the new one in this dialog window if necessary).
4. Click "OK". Click "OK" one more time.

Make sure you start recording with WM Recorder (or start its Auto recording mode) before playing any streaming video.

At services like YouTube flash video HTTP streams are cached by your browser. If you have already played your .FLV video you won't be able to record it with WM Recorder. I know only one stream recorder that can get flash files from your cache folder - it is Replay A/V.

To get these cached videos you can open the cache folder of your web browser and just copy the flash video files from it. Alternatively you may clean your browser cache, start recording with WM Recorder and then (only then) start your browser and replay the video streams so that WM Recorder can record them in the Auto recording mode.
