1. You will have to make a macro for each additional input. For example, video 5 would be the video 4 key and the tv/tuner key, video 6 would be video 4and tv/tuner key twice, video 7 would be video 4 and tv/tuner key 3 times.
2. I don’t really understand the question. Did you mean you know how to access the power on feature for Sony components only? The power on feature only applies to Sony components.
2a. You can add the power on function to the component or label key, for Sony components only. See page 43 of the manual. Then, if you insert the component key into the macro, it will turn on the component. Remember, if you are turning on a tv, there is a delay before the tv is ready to accept commands, so you can insert several presses of the timer key to delay the operation of the other macro functions long enough for the tv to warm up.
2b. There is no access to the power off feature except in the Sysyem Control 1 key. By the way, be sure and see this thread about System Control 1 and 3 keys

3. The AV3000 is NOT a two way remote, so it cannot receive information from a CD player, receiver, etc.
If you cannot do everything you want to do with the 3000, you might consider using discrete codes, which require the use of a RS/OFA remote, an additional expense but well worth it for the advantages received. See this thread if you are interested
