Is it possible to change an RCA output (video L & R audio) to one coaxil cable?  I want to get the output from a DVD player to various TV's around the house.

Search for "RF Modulator", I think Jaycar carry them ( but RF really is the lowest of the low in terms of quality. Have you considered pulling CAT5 and using CAT5 to A/V baluns?

I hadn't considered CAT5, would I need three run's of it though? 1 for video, left and right audio?

No. You can run all 3 over a single cat5e cable. There are various options available including regular composite, component or HDMI. HDMI requires 2 x cat5e runs.

so something like this then

How do you distribute it to various tv's?  can you just do it through a normal ethernet switch?

they are a 1 to 1 connection, if going to several tvs then you need a video splitter ahead of several of them at the source equipment end.

RF is not much worse then composite if you are not trying to mix it in with off air signals - all the noise from an antenna is what really makes it a lot worse.
