What are you using to plugin devices? Cable box, Digital Cable Box, Dish TV or ANT)
Really not that hard, and very easy to hook devices to this set.
Here's what I have:
HDMI - using Motorola DCT 6416 III Dual Tuner SDTV/HDTV DVR
RF - not in use (planning on using it though)
Video 1 - S-Video - Media MVP (network LAN streaming media of video and audio)
Video 2 - S-Video - wireless laser keyboard, mouse, WLAN, WWAN, laptop
Component - Philip Divx DVD Player
Component - FUNAI SV2000 VCR 4-HEAD HI-FI STEREO RECORDER + DVD RECORDER
I don't use the audio jacks since the HDMI cable carries digital audio so I use the DCT Optical Toshlink to my Pioneer Component DST/Dolby Digital Multi-Channel Receiver)
Both the DCT and Emerson have Digital Coax Surround Sound. But I have that used by the Philips so that's why I've opt for the Optical line.
