As the title says, I'm looking to update my JVC XV723GD player. My options are the Toshiba 4800 or the Panasonic RP62. Are either of these players better than what I already have? My JVC has been very good to me...it's a little disappointing on video-based material, but that's about it. Good color, good resolution...functionality...I'm just looking to upgrade. Or would either of those models be a downgrade? I did a search for info about these players, they seem capable players...but I wonder if what I already have is better.
