Hook a lead up from your Headphone socket of your stereo to your Line In port of your soundcard.
Make sure that the Line In Port volume is switched on. I can't help you any further as I don't use Easy CD Creator. I use Goldwave click here to record the audio in. Well worth the money. My advice is record the whole tape in, then cut it up and save each piece as an MP3 or something. Once You have all the tracks seperate, you'll be able to burn them onto a cd.
Just use a regular CD-R for burning.
