i posted earlier but my post was really long and i have not gotten a response yet so i am going to try posting again in a shorter way...
Can anyone explain their current connections to me or tell me if the connection below makes sense to them?
thanks in advance
Akai plasma tv
Comcast digital Cable box HDTV Motorola 5100
Panasonic DMR-E80H
Fisher DVD/Surround Sound System

Wall-Coax to Motorola 5100(cablebox digital/hdtv)
Motorola-Coax to E80 (do I need this coax connection?)
Motorola- SVideo to E80
Motorola- to TVs component 1 jacks using the component video outjacks on the Motorola(blue red green monster cables)This is so I am able to view true HDTV channels as the E80 cannot handle them..
E80 to TV- (yellow/red/white tri cable from component video out on E80 back to TV's component 2 jacks (since these are not real component cables should they be plugged in somewhere else on the E80? or into the video/s/s jacks on the TV instead of component 2?
Motorola- to Surround Sound system and to tv using audio cables only

Does this sound right? anyone have a better way?
Am I supposed to be using my comcast remote through the dvdr or should i be able to use the dvdr remote?
thanks in advance
