I have a perfectly good 27" analog tube TV...... butonly has one input....a coaxial input to the tuner.In order to use this TV for SD digital reception I amlooking for a VCR or DVD recorder that has atsc tunerbut also has built in RF modulator.Does anyone know if such units exist that are atsc andcan be used on ch 3?

DVD players rarely have modulators because the DVD system was introduced ata time when most new TV receivers had direct-video inputs.I'd check RadioShack -- they might have an outboard modulator.

Do any DVD recorders of VCRs come with RF Modulator for Ch 3 use?

Andy comments: I've run that setup and sometimes I see the copy protection and sometimes I don't,.... I suspect that some DVDs are copy protected and some aren't. If a person is using a his own DVD to make his own copy off-air, it won't have copy protection. Then, the playback is run to the VCR inputs and the Channel 3 output goes to the NTSC television... and it should work OK..

When VCRs quit, it's usually (in my experience) the transport mechanism. The other stuff is still workable, and using it as just an RF modulator should be very practical, unless you are playing back a store bought, copy protected DVD....... The broken VCR certainly has very little other practical use. Andy in Eureka, Texas

Yea, not only do the OTA stations now need the cable companies, the cable companies are (at least around here) heavy advertisers. It's a wonder that the TV staions even mention HD in their promos.

That's what I mean. They built Macrovision into DVD players. Did they put it in these boxes too? Maybe just downconverting to SD resolution was enough to feed the copyright sharks.

I really don't know what you mean. The "AGC fooling" Macrovision was embedded in the video signal. It was not built into the VCR. The "do not copy" flag is also embedded in the video of the DVD. It enables an anti-copy signal created by the DVD player and sent to a digital recording device. The "flag" must exist in the video signal. As far as I know, the video from digital TV signals contains no such "flag", so putting recognition capability into the conversion boxes would serve no purpose.

at that point one would have to remove the modulator anbd power it with a wall wart type power supply (old mobile phone chargers for example). usually in the region of 5-12v dc, you may also need a pot to attenuate the composite video signal so it doesn't saturate. i've saved a few old tvs without AV inputs by adding these little boxes so people can use them with dvds , video games , etc...

Actually, I mostly use mine for a tuner, although the transport works fine and gets used from time to time.
