You almost need a control -- a constant for an experiment. Another DVD recorder would be good to have around, for testing what's wrong.
It may even be an issue with the receiver's distribution, or the cables themselves.
I see posts in various forums, where people like to guess that it's copy protection. However, I'm not aware of any cable or satellite provider that is actually using the broadcast flags. You can read more about that at
http://en.wikipedia.org/wiki/Broadcast_flag. For one thing, it would go against the spirit of the Sony v Universal "Betamax case" where the Supreme Court upheld the consumer's right to record and timeshift TV programs. EFF has been at the forefront of fighting any limitations of this:

So copy protection is out.
Some devices are easily confused -- Toshiba and Sony DVD recorders, for example -- thinking they see broadcast flags or analog copy protection where non exists. But this is a LiteOn, and I doubt that's the case here either. However, the received may be mucking the signal up a bit, which could cause issues.
"RCA" is a misnomer. The red/white audio cables are indeed called "RCA audio cables", but "stereo audio cables" is more common since RCA is a trademarked name. The name "RCA" comes the company that invented the socket and wire type: RCA. But the video cable is not RCA -- it's a "
composite" cable, as it carries composite luma+chroma together on a single carrier. This is the yellow wire. While some cheap cables are the same wiring for all 3 cables, better ones may have stronger shielding or wire quality of the video cable.
Component is the RGB connector, three wires that also connect with an RCA-style connector, but the wires are generally much higher grade (or at least, they should be).
You generally cannot "crossover" your connection. In other words, s-video in must be s-video out, or composite in must be composite out. Most devices give unstable signals if a different output is used from the input. A receiver is a dumb device, so it will most likely screw up the video signal on a crossover connection.
Not sure if I answered you, but hopefully that helped?
