Record onto PC via "line in".... twin mini jack lead (red/white ends) from "video/sound out" on back of my music system, might be different outputs on yours, to "line in" which is a single mini jack.... can pick these two into one leads up from any audio shop mate....
On my PolderBits proggy I have option to select source....from drop down box of "aux, cd player, line in, microphone, mono mix, phone line, stereo mix or video"........
In FAQ's on Polberbits site it tells you all the info there under "connecting a turntable".... will be same for whichever recording proggy you use Dan ....
