So it seems like a digital connection from the non HD/BD DVD player will suffice, even for older 2 channel audio movies and a digital + analog connection from the cable box to the receiver to cover any eventuality.
The video connection will be component from the receiver(when HT is in full use) and coax from the cable to the TV for viewing without HT (WAF and just plain old crappy TV shows vs movies).
Will this setup cover all the bases?
