I actually use multiple connections out of the Voom box connecting to a Panasonic HDTV and a Sony Home Theater Receiver:
1. To watch Voom -- digital audio out goes to my home theater receiver, component video (Red, Green, Blue cable) goes directly to my HDTV.
2. For my TiVo -- RCA audio (Red/white) goes directly to TiVo, SVideo goes directly to TiVo (TiVo is then connected: 1. directly to TV via SVideo, 2. RCA audio to Home Theater Receiver, 3. "Yellow" Composite video to Home Theater Receiver)
3. To record to a VCR -- I run a Composite video cable from the Voom box to the Home Theater Receiver (then composite video cable and RCA audio from the Receiver to the VCR).
This enables me to: 1. Watch Voom directly from the STB; 2. Use the TiVo to record from Voom (without the Home Theater Receiver being on); 3. Record direct from Voom STB or from the TiVo. My receiver *will* convert the digital audio signal from the Voom STB and output it to RCA to the VCR.
Hope this helps!
The key is my receiver doesn't up/down-convert video between Composite, SVideo, or Component, thus necessitating redundant connections.
Best wishes,
