I have tried about 5+ cables for my iPhone and have gotten mixed results here are my conclusions
There are three kind of cables that you can connect to the iPhone
1) the first type simple does not work, no video ouput and the cable will just say that the iPhone does not support the cable ( this refers to the headphone A/V cable and others of the like)
for example these will not work http://www.chinawholesalegift.com/p.../Ipod-cable/AV-Cable-For-ipod-16492542491.jpg
2) the second type will play a movie for about 60-90 seconds, eventually it will stop sending the video out signal and tell you that the accessory is not supported. This is typical of the cheap av cables you can buy on eBay right now, and some of the older ipod dock connector cables. Basically any cable that does not SPECIFICALLY say "made for iphone 3g) will stop sending a signal awhile for example these ( bought and did not work )

3) The third type of cable works, and works most of the time but occasionally it will stop sending out the video signal. My theory is that it's a loose connection. In order to restore the video out signal you will need to hard reset your iPhone (hold power and home button for 10 seconds). Cables like this include the official apple A/V cables and the Schoshe cables

These worked on my living room LCD and my indash 7" LCD ( so far best only cable that works in my car)
Video output will only happen from three programs
Youtube
Ipod Video
Ipod Photos
No other programs, events, messages, screens, etc will display video
Video output currently not working ( hopefully soon)
Truveo
