Based on your description, it does not appear you can connect directly from the receiver out to the TV speakers. Your options would be to then just go straight from the HT/DVD tape out into the TV line in, bybassing really the HT component of the HT/DVD combo. The sound will be thin basic TV sound, not so exciting for movies.
Why not simply get a pair of bookshelfs with decent size woffer (6/12 inch) and place them at equal lengths from the TV.. that way its still simple, but with fuller sound.
