Macbook+Tivo=No DVD Showing up

Question

I would like to use my Macbook to play DVD movies on my TV. On my current setup I have the Tivo connected to my TV with A/V plugs (Yellow/Red/White).
I went to the Apple store and bought the Mini DVI to Video adapter, an S-Video Cable, and a Monster Audio cable that plugs into the headphone output on the MB and they Y's off into two Audio A/V plugs.
I tried to hook it up and watch a DVD and nothing happened. I have the S Video cable plugged into the DVI-Video adapter (which is plugged into the computer of course) and the other end plugged into the S-Video Output on the back of the Tivo. I have the Monster Cable plugged into the Headphone jack on the MB and the other end to the Audio Outputs on the back of the Tivo.
Turned everything on and nothing worked.
One thing that I think I am missing is someway to tell the Tivo to switch to the "Auxillary" output. How do I do that with Tivo. Thanks for everyones help.

Well, I had been writing something else but I'm gonna forget it and just try this again.
You need to get audio and video to your TV. Currently, with the set up to the Tivo, you have an S-Video connection on the Tivo end, which means you would need to use that to connect to your TV. If your TV has no S-Video, then that can't be done with that adapter you have. The Audio you have in a headphone jack to the 2 colors of composite cable for the left and right audio. That is probably more useful, as most TVs have composite inputs, but that would only give it the audio, and you would still need the sound. The easiest way is to have an adapter from your MacBook that has 2 cables on an end, one for headphone jack and the other for the mini-DVI and it switches it to a 3 cable (Red White and Yellow) Composite end that then you connect to the 3 color composite connections on your tv where the Tivo gets plugged in (unplug your Tivo and plug that in when using, it will not affect the Tivo and its recording process or anything) or if you have a second set of composite in connections on your TV, plug it in there and change the channel to the corresponding one (my TV has AV1 (tivo channel), AV2 (the side inputs which we use for the XBox) and FRONT (I have no idea what it is for as we have no front inputs at all, heh).
I have no idea if there is an adapter like this or not. I know that my portable 7 Inch LCD screen DVD Player has a nice little port on it that I use to attach one end of a cable, and the other end has the 3 color composite cables on it so I can connect it to a TV for DVD viewing (and it automatically turns off the display on the player as it is not needed). But the MacBook has that odd mini-DVI plug and I think they expect everyone to have tech TVs that are plasma or lcd and have S-Video and component inputs, DVI and/HDMI etc. Mine doesn't. Coaxial and Composite cables are all it has. But if you could find an adapter that took the mini-DVI and had the other side the same as the portable DVD player plug port, then you could use that cable to attach to it and then to the TV (I could even send you mine if it worked as I never use the cable much less my DVD player anymore as I have 3 laptops now).
Demand a mini-DVI to tri-color composite adapter if one isn't available... I would buy one. Maybe... I can't use any of the other types though thats for sure.
Sorry, I tried my best...
