Upgrading the power supply section on a DVD player will increase the performance of both sections ( audio and video ). As usual, the "usual" culprits that you'll find recommended are Stan Warren, Ric from EVS, Dan Wright, John Hillig, etc... They are basically upgrading capacitors to models with a lower ESR / possibly higher amounts of reserve, "fine tuning" the sonics of the audio path via parts swapping ( resistors, caps, wiring, etc ) and sometimes removing unnecessary filtering / components. This typically results in increased liquidity, smoothness detail and "musicality". As to the video improvements, you should see more contrast and lower noise on the screen from the increased power supply capacity. Sean
