Hille. There's a program called RecAll Pro. I use it like a VCR to set the time it turns on a record function. YOu can select the input such as "What You Hear". This way you can set your computer to do streaming audio. Then set the RecAll Pro program to turn on at the right time.

BTW, You have several time zones here in Canada. Atlantic Canada at 6:30PM would be 5:30PM Eastern. West Coast(Pacific) at 6:30PM would have been 10:30PM Atlantic or 9:30PM Eastern. So, it is about to start in BC in about 16 minutes
