The next time this occurs, can you send the log file to us? You can find it by going to File|Reveal Log File... in the menu. Do this after visiting a few sites such as YouTube when it doesn't pick up anything.
Another option is to set a minimum download size in the Preferences under the Downloads tab. This would only work if the videos you are capturing are all larger than the songs.
Unfortunately there is no way to specify certain tabs in the browser. Jaksta doesn't really work that way, it just sees various streams with different types of data and has no way of knowing how the browser intends to display them.
I could put forward suggestion for a "Don't Capture Music" option in the Preferences, if you think this would help you out.
