My home theater is not what you’d call impressive or up-to-date. In fact, the TV is more than 20 years old, I bought the stereo 10 years ago and the CD reading laser has long since burnt out (but the speakers still work) and the DVD player is made by Daewoo (you know, the same company who makes cars with a logo that looks like a pair of underpants). So, even though it’s not all that impressive, I enjoy watching movies.
I have a decent grasp of entertainment systems and knowing how things work generally, but a while ago, when we bought the underpants-logo DVD player, I ran into a problem that had me stumped. In case anyone else runs into the same issue, here’s what I learned.
The TV is the same one my in-laws used when my wife was a little girl and it’s so old it only has input for a coax cable. My VCR has audio/video RCA ports and coax ports, and the DVD player only has RCA ports. The stereo has auxiliary audio RCA ports.
My first try was to run the DVD player through the VCR, but when I played a DVD the screen looked like someone was holding a magnet up to it every few seconds. The picture would go from great, to awful every 10 seconds or so. It wasn’t satisfactory. I later learned that this is done to keep people from recording DVDs and the only solution is to buy an RF modulator. I picked one up along with a video cable at a nearby Radio Shack for about $20.
The RF modulator now receives the DVD and VCR video outputs and then sends the signal to the TV through the coax cable. The signal from the cable provider goes into the VCR as well. My only problem now is that the RF modulator only has one audio input, so I either have to switch audio cables between the VCR and DVD player in order to get the audio through my stereo, or just leave them and use the TV when we use the VCR (which is what we do now). I could also buy an audio splitter but I’m not that concerned about it.
Here’s an article explaining the details of why you need an RF modulator and since this is a prime example of a picture being worth 1,000 words, here’s a diagram I made that illustrates my setup.

You forgot to mention that our underpants-logo DVD player has stopped working after only 1 1/2 years. Piece of junk!
» Comment by katie on August 29, 2005 @ 10:45 amTrue, the Playstation is now acting as our non-underpants-logo-DVD player.
» Comment by dan on August 29, 2005 @ 10:48 amI had to do the same thing with our DVD player. I was so annoyed at spending 20 bucks for a work-around for Hollywood’s collective paranoia that I ripped the movie I was trying to watch and put it on the intarweb.
Well, I would have if I wasn’t so lazy. I made do with a few mumbled epithets instead.
I did shake my fist in a westerly direction, though.
» Comment by mckay on August 29, 2005 @ 11:40 amis it the ps original or the ps2? only because you mentioned everything was old.
» Comment by whaleman on August 29, 2005 @ 2:03 pmmckay: Well at least you thought about it, and I’m sure the fist shaking towards the west felt good.
whaleman: Good question. The Playstation is a shining exception from the rest of the components. It’s not only a PS2, but the new, smaller one (almost the size of a paperback novel).
» Comment by dan on August 29, 2005 @ 4:42 pmThe real question is “Why even bother?” Get a new stereo and TV instead of wasting time and effort on that old crap. That’s like explaining to us how you managed to find a software workaround to get your 486 DX4 run Windows XP. Sure, it works but why even do it?
Just my two cents cousin.
BTW, I just tried to post with nothing in the E-mail field and it gave me an error saying that it is required. Your page shows it as optional though.
» Comment by Rick on August 29, 2005 @ 10:04 pmRick: Why do it? Because you can (and I’m a miserly tightwad). Plus, not everyone wants to have to buy a new stereo and TV to get their DVD player and VCR to work.
Thanks for letting me know about the optional e-mail issue. That’s a result of the upgrade.
» Comment by dan on August 30, 2005 @ 9:24 amNow, i have the same sort of setup on my tv in the bedroom and i have the video going from the DVD and VCR through a single rca (the yellow) to the RF modulator and then the red and black rca connections going to the stereo. Then you just turn the tv’s volume all the way down and you can enjoy stereo sound on all components. even if you only have the triple rca cable r/w/y, you can usually split the yellow off by just pulling it like a licorice from the pack.
just my $0.02..
» Comment by Darren on October 19, 2005 @ 10:31 amI have a new girl friend who asked me if I was able to hook up her dvd to her older tv, no one else could do it. So I will run out and get an RF Modulator and maybe get lucky tonight!!!! ha!ha!
Thanks (I’m glad that “you bothered” to post this!)
» Comment by Kevin on August 28, 2006 @ 2:17 pmGlad to hear I’m bringing people together through my blog.
Best of luck tonight.
» Comment by dan on August 29, 2006 @ 7:23 amMy father has a very old floor model TV with a cable box hooked up to it. There are no cable inputs in back of the TV, just two screws for a antenna if he didn’t have a cable box. I recently bought a Panasonic vcr/dvd combo & hooked it up & the VCR works fine but he gets picture distortion when playing a DVD. Would a RF modulator solve this problem, other than the fact that he needs a new TV? Also, would it help to put in red/white/yellow cables from the cable box to the dvd/vcr combo?
» Comment by GaryB on September 14, 2006 @ 4:04 pmGaryB: Yup, an RF modulator will do the trick.
» Comment by dan on September 14, 2006 @ 4:33 pmthanks a lot dude!! i have an old tv with just a coax too, so when we got this new dvd player with only rca output, a couple of days ago, i was like what the f*&$!!?? how do i connect this damn thing?
hopefully an rf modulator will do the job!
» Comment by vick agnews on September 21, 2006 @ 3:46 pmVick: Yup, an RF modulator is exactly what you need.
» Comment by dan on September 21, 2006 @ 4:54 pmIt isn’t just misers who “bother” with this kind of thing. People like Rick say “just go get” new stuff as if there were no $ or waste involved. That plastic card you throw around has real consequences, as does treating objects and income as if they were truly disposable. Those of us (disabled) on limited fixed incomes appreciate stuff like this. Anyone who cares about being responsible does. Your purchases and your garbage are important. Advertising is largely a shame-based industry. Make intelligent choices . . .

» Comment by dan on December 22, 2006 @ 1:45 pmwow i’m only 13 and this site really helped me because i also have a really old tv and i just bougt a new dvd player and i couldn’t hook it upand my dads no good at this kind of stuff so… thank keep up the good work it is really helpful
» Comment by Carly on December 28, 2006 @ 8:35 amSo i have an older model TV, NO VCR, cable box, DVD and of course my RF Modulator.
» Comment by Katey on January 19, 2007 @ 4:43 pmHelp!
I can’t the three to talk to one another. What am I doing wrong?
Katey: It’s hard to say. What do you get when you try to play a DVD?
» Comment by dan on January 19, 2007 @ 9:09 pmI have an older floor model tv, RCA XL-100 since 1985. Serviced only once. and still running good w/good picture and sound. However the remote control has long met it’s demise and I haven’t found another matching remote control in 10 years. Universal remotes just don’t connect. Where or who might have a remote for the old RCA XL-100?
» Comment by D.Moses on January 24, 2007 @ 6:03 amEbay would probably be your best bet, or you could try posting a wanted item on freecycle.org. It might be worth trying other universal remotes. As far as I know they’re supposed to work with all TVs.
» Comment by dan on January 24, 2007 @ 7:34 amtry http://www.replacementremotes.com, they have quite a variety.
» Comment by Debi on January 26, 2007 @ 10:53 amThanks for this post –this has really helped me out with my older pieces of crap –some people (?) have to live with it & make do with what they have.
» Comment by mgamer on April 26, 2007 @ 7:28 pmyello
ta very much for this! i’m exhibiting some of my video work and wanted to show it on a real retro tv (looks so much cooler than an ugly silver/grey plastic box) - had tried dvd player thru video player to tv before and it worked! but this seems easier and more reliable. so i’m off to get me one of those rf thingys. yup.
