Samsung LN52A750 PIP Function...Not User Friendly

The HD and Digital picture on this TV is amazing. However when it is in the PIP mode (which I love when watching two games)to beable to watch two diffrent broadcast at one time, this TV is not user friendly at all. You must use the menu to select from a hold list of options to change the channel when using the PIP function. You also must bring up the menu to again select from a hold list of options to switch the sound between the two PIP channels. Also the sound between the two channels are uneven. One can be very load while the other you can hardly hear and must adjust the volume every time. Other TVs I have had there was a switch button on the remote for simple PIP functions.
