OK this is what i did today this may or may not help you. First i used the flashback button on the remote. Example-------My componet video is on video 3 and my cam is on video 4. Set the tv to video 3 then goto video 4. Now to switch back to video 3 just push the flashback button. So what this does is you can send a flashback button push to switch back and forth from each othere. Here is the 2nd one. you can push the source button then push the number key that you want to go to. Example--------same as above but with a source button push then a number button push. Video 3 to video 4. One source button push then the number 4 then one source button push then the number 3 for video 3. Its a pain in the ass but its right now the only way to get the tv to switch untill i can or someone can get the direct codes from sharp. Which will be will lets see NEVER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!. Welcome to high end AV. :)
