oh and by the way this mod worked for me. if it doesnt work for you and you botch your box, it is not my problem and you might want to not botch your box next time.
this mod allows you to have rca jacks on the back of your box, for composite video and left and right stereo. i am working on adding svideo out.
my box is a:
v1.5
40gb 7200rpm maxtor
tsop flashed baby
and no more a/v cable!
to start open your box and remove all components (i.e. hd and dvd drive, as well as cables and anything attached to the motherboard)
it should look like this
next remove the board from the box and place it on an est bag. flip it over and you will notice the bottom side of the a/v connector to which you will be soldering
here is the pinout and wiring diagram for the A/V connector. the color coded lines indicate where you need to solder. the right audio channel attaches to pins 1 and 2, the left channel are pins 14 and 15, the video jumper are pins 7 and 17, and the NTSC video is pins 23 and 24. make sure you have the wires connected correctly and there are no jumps because will probably short the board when you turn it on.
once you have your wires all soldered on, fish them through to the topside of the mobo. like this! YAY! learning is fun!
now flip the board over and solder on your rca female phono jacks, LIKE THIS!
at this point i put my box back together and remounted everything with all the screws and powered on the box, now this part is what is going to determine whether or not you screwed up, so cross your fingers. if all goes well continue on, otherwise you might want to figure out where the short is and try again, and again it is not my problem and you do this at your own risk.
next, remove everything, including mobo from the box and map out where you are going to mount your rca jacks. use a drill or a knife to make the holes to mount the jacks. mine looks like this.
finally put everything back in the box, screw it all down, and bam....you are done. this is what mine looks like, feel free to comment and ask questions.
