Hi...At my girlfriend's house, in her room, she has:
A dvd player A VCR A TV that only accepts RF
Judging by just the things that say "IN" and "Out", no more equipment would be needed. This is what I tried:
DVD (via composite) goes to "In" on VCR Antenna cable goes to "Ant In" on VCR VCR RF-out goes to TV
Now, it seems like that should work, but it doesn't. The VCR and antenna work fine, but when the DVD player is run, it doesn't go through the VCR to the TV.
Set the VCR input to line. You will probably need an RF modulator. In most cases a DVD player can't be connected through a VCR because of copyguard problems.
