Just got my Dynex 3.5 mm a/v cable in the mail and it works great! $4.95 plus free standard shipping at procablesdirect.com. The same exact Dynex cable was $40.99 at Best Buy before tax!! The red end works in the yellow port and the yellow end works in the red port, and the white end goes in the white port. No problems with audio or video output on my tv, for those trying to set up their tv out function, use the NTSC and the AV2 input on your tv if you are connecting the cables directly to your tv. If you are connecting your cables through a dvr/blu-ray/dvd player, change your tv input to AV1 to match the set up. Good luck!! It was worth the time to figure it out.
***I have the samsung galaxy s vibrant with firmware2.1 update 1, phone is not hacked, and the tv model is Dynex 32" 720p***
