>>>CURRENTLY I HAVE THE DIG. AUDIO OUT FROM THE CABLE BOX TO THE HTS. IS THERE ANY ADVANTAGE TO RUNNING THE DVI FROM THE CABLE BOX TO THE HTS VS THE COMPOSITE STRAIGHT TO THE TV? ANY HELP WOULD BE APPRECIATED.>>>
I need to separate your question into two:
1. Is there any advantage to running the DVI cable vs the composite?
2. Is there any advantage to running the cable from the cable box to the HTS vs straight to the TV?
So to answer #1 - definitely yes. Composite is analog, and not the best kind, and DVI is digital.
To answer #2 - it depends on what other components you have and how you want the source switching to be done.
If you connect CBL -> DVI/HDMI -> HT, then the HT will be doing the source switching for you. Assuming your TV is always connected to the HT receiver via HDMI, you only have to push one button on the HT receiver to switch both 'Audio' and 'Video' inputs.
It is also possible (I am not familiar with your HT, but most do this) that when watching CBL you hit the Play button on the HT, the correct source will be selected for you automatically.
If you connect CBL -> DVI/HDMI -> TV, then you'll need to
1) select the proper AV source on the TV;
2) select the proper audio on the HT.
In any event, it is never better to connect your CBL to TV via an analog cable when a digital link is available.
From best to worst: DVI/HDMI > Component > S-Video > Composite > Coax (RF). (All but DVI/HDMI are analog).
