Hello everyone......first post in this forum. I now have what I regard as an excellent HC system. I currently have: Denon 3805. Pioneer DV656A-K component and coax to Denon. Sky+ JS RGB-YUV and optical to Denon. Component from Denon to PDP50MXE-1. I am looking at various options for my next addition/upgrade. One of these options is improving picture quality with a scaler or other device. I have had no experience with scalers, and I would like to know what your recommendations or suggestions are. I am fully aware of the HD issues regarding my display, but I would like your suggestions based on current and future compatibility. Thanks everyone. Johnny.
