If INPORT is the same as most of the other audio capture/track splitter devices the main problem will probably be that when attempting to split the one large .wav track back into the individual song tracks, the program can't distinguish between the end of a track, and a pause in the instrumentation, resulting in a music track getting split into more than one track.
I use an Edirol Audio capture device (EDIROL UA-1A) to record the one giant .wav track to the hard drive, and then use another program called LP RIPPER
http://www.cfbsoftware.com which allows you to manually check and correct each track to correctly spilt them into individual tracks.
They would still have to be swept in KHP, though.
I do it with LP's and Cassettes to archive them to cd's, and this is the only software I've found that will correct the error that a pause in the instrumentation causes, but you must do it manually. I've no exprience with INPORT. Maybe it does this also.
