(All of the equipment mentioned is from the 90's before HDMI, flat TV screens, etc.)

I play DVD movies, music CDs and MP3s from a Sony DVD player, but I have to switch the RCA yellow, red, & white cables between the front of the TV and the back of the receiver. They're in a cabinet, so it's a big hassle. If I got some RCA Ys and left the cords plugged in to the TV and receiver at the same time, will it cause interference hums or anything else negative?

Loss will be a factor. There are commercial audio/video switches available. They used to be very common before HDMI world.

Loss won't matter much unless it's big. I can unplug the TV cords while I'm listening to music, but not the other way around.

I was in a similar position some years ago, and I went with a switch. It worked nicely. I never had to get in the dusty hell hole that was the back of my set ever again. Or fiddle around with RCA plugs.

On my old 90's era setup I had the digital output from the DVD connected to the receiver and the analog outputs to the to the TV. Worked like a charm - no plugging/unplugging necessary.

Just don't cross the steams. NEVER cross the streams.

It is what it is.

Yes you can. Been there, done that. If you get any problems, you are out a couple of bucks only - just try it.

You can even get one with a remote for a couple bucks more! (I used to have an HDMI switch w/remote in the days of paucity of HDMI inputs - ended up programming my Harmony remote to do the switching for me based on what activity i was doing....

It will be fine. I once hooked up a DVD player to two TV's at the same time, composite video with a splitter, no problem.
