It will probably be fine, but there is always a danger if you exceed specs. If it were me, I would give it a try.
Depends on what the output voltage on the converter is.
Yes. You can tell if the adapter is warm then there is a waste of energy. It is the excitation of the transformer that is causing the heat loss.
Some 9 V adapters rated for 1000 mA will provide 9 V at 1000 mA. If you use it on a 200mA device the voltage may go up to 10-15 V and if that device can not handle the higher voltage, it it could burn out. Better adapters will only put out 9 V exactly and have no problem. Be careful of revere polarity where the positive on one is the negative pin for the other adapter.
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
The answer to this question is yes. The 30 volt adapter will supply twice the voltage required by the 15 amp appliance. The other thing is that 1 amp is equal to 1000 mA. Even if the voltages were the same, the output current of 1000 mA when 1100 mA is needed, is not enough to supply the appliance.

No. You should use the adapter specified for the DVD player. Using the wrong adapter can damage the DVD player and/or the adapter and/or cause a fire.

No you shouldn't use a 14 volt 5 amp adapter on a 12 volt 5 amp device unless you know for sure that the 12 volt device has an internal voltage regulator that will lower the voltage to the correct voltage range the device was designed to use. As long as you always take care to check the output voltage with a voltmeter first, to be sure that the voltage from the adapter is regulated, meaning that it does not rise when a lower current in amps is drawn from it, you may be able to use an adapter that gives the right voltage at a higher amp output rating than the device actually takes. (For example, it may be possible to use a 12 volt 7 amp adapter for a 12 volt 5 amp device.)
Yes, this can be done. The adapter will handle at 120 volts x 15 amps = 1800 watts. The adapter is just a step up transformer. The maximum 220 volt device that can be connected can only have an amperage rating of 8 amps at 220 volts.
15% of 1100 = 165
0.0136
15% of 110,000= 15% * 110000= 0.15 * 110000= 16,500
It sounds like you are referring to a universal adapter. A universal ac adaptor has several tips, which adjust the voltage and amperage, and the higher the voltage, the lower the amperage. Therefore, if your adapter is 4.3 amps at 15 volts, it will be significantly lower amperage at 19 volts.
