You mean the TV's A/V inputs surely? This might be your problem if you're confusing the two.
Also it kinda sounds like if your inputs are toast, you were using the VCR to pass a RF moudlated signal to the TV? The Liteon doesn't work that way, it's RF input and output are pass through for the RF signal only. Can I suggest patching your VCR back into the system and continuing to use it as a RF converter. Use the A/V inputs on it to take the feed from the Liteon.
I know this is a bummer, I felt the same way when I found out and wasn't able to feed my upstairs TV's via RF. I had to buy a cheap RF converter to do the job instead (no room left to retain the VCR).
