I own a 40" Samsung LCD HDTV with 1080i resolution (native 720p)? I am choosing between the 3 Oppo DVD players that will work well in 720p or 1080i resolution. (All players can upscale up to 1080p) 1. Oppo DV-980H 2. Oppo DV-981HD 3. Oppo DV-983H I prefer 1 and 3 since they are USB 2.0 compatible. But I want to find out in terms of video quality. (upscaling dvds to 720p or 1080i) Thanks in advance.
