The other HD DSS receivers that I've used exhibit
the same characteristics. Even the new Zenith
model says that it will not output HD and NTSC
simultaneously. If someone made a box that did,
it would justify everyone in this industry to
use that box 100% of the time over any other manfacturer's
model no matter what... hint, hint.
according to one of the installers here there is a receiver out there that does this. The Sony SAT HD100 --- used it at a job specifically for this reason, HD ouput used in the theater and SD output used in the kitchen at the same time.
