Theres laws to being on this forum and you've broken one of them.
You must know absolutely everything about everything computerwise so you don't have to ask questions.
Anyway, this is a question that I still get asked so theres many more like you.
If you've got 3 music CD's that total 137 minutes then you are still bound by the 80 minutes on a blank CD.
Your only way out is to buy a new CD player that will accept MP3's and you should get 800 mins at 128 bits.
128 bits is the sample rate of the MP3 but you will get less on if you raise the sample rate.
The other way (as mentioned) is to look for AUX in on your CD player and buy an MP3 player.
I've just bought a marvellous little 2 gig Archos for £40 thats going to be played over a 3000 watt PA system.
