OPPO BDP-93 RAM Modification Thoughts.

Just buy a 95 and forget the mod, which are never cost effective.

I would but I think the audio/video in the HDMI is same for both.

You could try giving Ric Schultz a call over at EVS (Electronic Visionary Systems - you can Google "EVS tweak"). He's 'officially' discontinued his mods of the 93 and is currently offering mods on the 95, but he may be willing to do something for your 93 if it's a small enough mod possibly. I've dealt with Ric and Kyle both, but tend to prefer Ric's approach to things as to me his mods in general seem to offer better value. But, go to his site and take a peek and you'll find his phone #.
