subject: CableTV in stereo?

-=> Quoting Dennis Lewis to Mark Madronio <=-
 -> The TV displays the word "Stereo" when showing off-air channels, why
 -> doesn't it do the same on the cable channel?
 DL> The VCR output on channel 3 or 4 is modulated with a mono output RF
 DL> modulator in the converter.  The only RF converters that I have seen
 DL> that have stereo outputs are those on cable boxes.  With VCR's costing
 DL> less than $200 and cable boxes costing $350 you wont likely find a VCR
 DL> with stereo outputs on the RF as you get better sound and video with
 DL> the Audio video line outs.
 I didn't know that they can have stereo RF outputs. I've just attached the
 cable box to my hifi for clearer sound. Too bad that I don't have enough
 A/V-in sockets on my TV to connect the video portion too.
 ->
 -> Also, when the VCR is OFF, the TV can show the cable channels OK, but
 -> if the VCR is ON, it looks garbled. Anyone know how to fix this?
 DL> When the VCR is off the antenna signal is sent through WITHOUT being
 DL> demodulated and re=modulated by the VCR.  It simply loops through.
 DL> When you turn on the VCR your TV is getting a signal from both the AV
 DL> inputs AND from the antenna causing interference.  Try turning the
 DL> TV/VCR switch on the VCR to OFF so that the RF output is turned off
 DL> when the VCR power is on. Some newer VCR's manufactured by Matsushita
 DL> (RCA, GE, Panasonic) have an option in the set up to permanently keep
 DL> the TV VCR switching turned off when one uses the A/V outputs.  When
 DL> the VCR is turned off, the unit switches the antenna into the loop
 DL> through to TV mode but it does not activate the RF modulator when the
 DL> VCR is in the PLAY mode or when it is first turned on, which is the
 DL> normal logic with most VCR's.
 Thanks for the explanation. I've forgotten all about that ever since I've
 gotten a TV with A/V sockets.
