[QUOTE="joetama, post: 4139196, member: 564641"] Don't use a cheater plug... Never use a cheater plug for anything other than diagnosing a problem. Never use them for a long period of time. Damage to your system or injury to yourself of someone else could occur. There is a reason ground plugs are used. That being said, make sure that your receiver and the DVD player are plugged into the same power source. Make sure that you have a solid ground. Make sure that your RCA (analog I assume) are firmly seated into the plugs. Try using different outlets to see if you have a bad ground or stray voltage on the neutrals. If this doesn't fix the problem, attempt to 'lift' the ground by using a cheater plug. This is a cheater plug.
