The DTA only provides RF output. If I connect a coax cable between the DTA and the TiVo, the TiVo will not be able to tune the signal due to the bad tuner.
I would like to get an RF modulator to convert the DTA output from RF to composite. I would then connect composite audio/video cables from the RF modulator to the composite inputs on the TiVo.
However, I was wondering if anyone knows whether the input source on the TiVo can be manually selected when a DTA is set up? Or would the TiVo force me to choose the RF input when using a DTA?
You can use an old VCR as an RF modulator.
Get one with selectable line inputs for flexibility's sake, if possible.
Also better to have one that's stereo to assure that the built-in modulator does stereo.
Have you ever checked that TiVo's power supply for bad capacitors?
Maybe it's not the tuner after all.
What's the model number of the TiVo?
You might be able to find one free or cheap on Craigslist and transplant the tuner if it is bad.
Or if you're really adventurous, transplant the crypto chip to move the TSN (to which the PLS is tied) to the new motherboard).
Or transplant the power supply to see if that makes a difference.
If you plan to keep using that TiVo it wouldn't hurt to have something around to cannibilize for parts.
If telling the TiVo you have a cable box doesn't work, you could lie to it a different way and tell it you have a satellite receiver hooked to the line inputs, just make sure there's a video signal on there when you do the setup.
