    ok so I have these boxes (see pic, fig. 1) and the continuation of my science demands that I harvest its LEDs, inputs, outputs, caps, resistors etc. but then I noticed the out enclosed by a red circle in fig. 1. Now my noise engineering demands that I attempt to use these as a converter to convert my analog guitar output into a digital signal for my PC (for reasons I donno, my pc hears analog fine, my heart wants digital) as I have sought forever now. I pose to you, gentlemen & gentlemen, these questions and bear in mind your answer will either save or condemn the lives of these pay-TV boxes.

    Can I use these as an analog-digi converter somehow, willing to solder? what CAN I do with them besides pay for tv? if these boxes are meant for doing science, anyone got a simple, radioshackless converter circuit diagram?
    thank you.

    your PC already converts any analog input into a digital signal for storage/playback ... so you have nothing to gain

    The audio portion of a cable TV channel already is in a digital format, as is the video. There might be a digital-to-digital converter to make an output that is compatible with home entertainment audio gear, but the only place there is any analog audio in that box is at the red and white connector outputs.
