Hello all, I was wondering if anyone knew where to find a cable that would hook my video and sound cards to an older TV (coaxial) and still use the TV's speakers (console game style). I'm asking this beacause I have a laptop that I want to give presentations on, and it's screen is too small, and the speakers are not exactly loud.. . Plus I'm not to good at splicing cables.

The ports are:
Audio: Left channel, Right Channel
Video: VGA, or DVI
can anone help?
