Instructables
Dvd player as a computer monitor? You remember that we used a composite monitor back in the Mythtv instructables. (http://www.instructables.com/id/Setting-up-a-computer-based-DVR-with-Mythtv-for-l/). Here we are going to do a variation on that but use a dvd player as the monitor. Though I meant this to be for text based server and computers Certain low gui desktops could work also.

Most but not all computer servers are going to the command line I.e no graphics. Even as I understand it, MSWindows 8 server is going to the command line. Never hurts to have a back up monitor for an emergency, for portability, or if you just want to go retro.

Note: Tried two old portable B&W tv's and it did not work.

Update: Using the dvd player as a monitor for Raspbmc!

Step 1: Computer video output.

S-video was a step up from the old composite video from earlier computers. Actually it is still around if you look at your video card or the back of your computer you may see an s-video port. Even some of the newest cards still support s-video.

Step 2: Adapter cables and adapters.

Harder and harder to find, but you still can get the cables and or adapters. S-video cables usually come in three varieties, They either are composite and audio or chroma, luma and audio.  Some adapters only have composite video. That is what I used for the pictures here. Found it at the 99cent store of all places.

Note: The Comodore 1701 and related monitors supported the chroma and luma inputs.  No connection to Cyber Technology.

Step 3: Make your own adapter.

(Try this at your own risk!) If you care technically inclined you can hack an s-video extension or male jack. Just get a 470 pF capacitor.  Should be under a dollar.at your local electronics store.

Note: Have not tried this myself yet.

Step 4: Technology can surprise you.

Your results may vary, but it worked for me.screen hooked to ald PC to see what would happen.

If I were you, I would rip out the DVD readers and place the raspi, then put in a voltage regulater to power the pi off of the player's battery. Bonus points for a miniature keyboard intagrated somewhere

Sounds like an interesting idea. Do not have a spare dvd player. I will probably just get a case and use double stick tape to attach the RPi to the back of the player, We dislike one function devices. Multi-use is more practical...
I've had a similar idea.. Just scavenged a Sylvania 10" DVD player from the junk yard.. Found out the reason the person tossed it, apparently someone in quality control missed where the ribbon cable for the LCD/Speakers went in the base, and crimped several wires of the ribbon, between a screw mount. (they layered 7-8 wire sections of the ribbon op top of eachother, and tightened the screw for the base to the middle/keyboard, right on it.. Video looked Horrible!) Now.. Looking at a detached LCD/Speaker panel, with a ZIF strip, and no source for the connector pin-out. Small as it is, it's about the right dimensions for a HD, but I'd be darned if I could figure a way for connecting it to the HDMI port of the RPi.

If you go to fcc.goc with the fcc id, you might be able to score some documents.
