It's all about pixel mapping and lack of noise. Bravo does not add EE, sharper, more neutral colors, and less noise on dark scenes (mild macroblocking) than the Zenith DVB318 (DCDi deinterlacer, unknown MPEG decoder) via 1080i component (its DVI is too bright and 720p is softer due to YC mismatch) or HD941 (DCDi deinterlacer/Zoran MPEG decoder) at 720p HDMI (1080i is same).
Heck HTPC is well touted as the best and with appropriate muscle power, software tweaking it probably is. My HTPC is an average performer and Bravo D1 beats it without hassle (once you've modded it). I've been HTPC fanboy for years (6 years usage). I do use the average but adequate gear (Radeon 9800pro, Dscaler codecs, FFDSHOW with 2X resize, unsharpen sharpening filter, 3D denoise, and bicubic with chroma/luma sharpening at 1.3). I still use the HTPC for WMV (HD), SDTV (using Dscaler4 and Svideo capture from SVHS tuner/VHS tapes), MP3, gaming, and *.ts files.
I've tried LiteON LVD-2001 (sigma 8500 like the Bravo D1 except no DVI--component sucks on D1 too but better than LiteON LVD-2001) at 1080i component, Neuneo HVD-108 (AMLogic chipset) at 1080i component or XGA via VGA, Zenith DVB612 (Zoran 888) via 720p HDMI, and Sylvania DVL-1000G (nonDCDi, Panny deinterlacer and MPEG decoder--Panny S52S clone minus the DTS output via SPDIF), Panny RP62 (DCDi but 480p component only), Sharp DV-S25U (DCDI 480p component), and Samsung HD755 at 720p HDMI (Zoran 778--fails blacker than black on PLUGE test) with HD1000u.
Bravo D1 is best of these players. I wish I have the Oppo 970HD or 971/981 to try but I don't want to spend more right now (eventually the curiosity bug will get me)
