The major knock against the BDV-E770W is the lack of any HDMI input connectivity. Competing systems such as the Samsung HT-C6500 and LG LHB975 both offer two HDMI inputs, plus optical and analog audio inputs. Even Sony's $300 HT-CT150 sound bar has three HDMI inputs, so it's a bit puzzling why the BDV-E770W doesn't have any. If you can live without HDMI, the BDV-E770W has a decent selection of audio-only connections, including two digital audio inputs and two analog audio inputs. You can connect three external devices overall, which is about one less than most other systems.
