Samsung R121 tv signal interferes with SAT TV. HELP

I have a new Samsung R121 recorder/player with:
TV in (antenna)
TV out
SVHS out to projector

The TV signal creates interferences (shadows) when viewing SAT TV or DVD. If I disconnect the TV IN (antenna) the image from SATTV and DVD or DVDbecomes grainy and fuzzy.
I have tried every thing, and nothing gets better. This same problem I had with a previous recorder (Packard-Bell)

Any ideas?
