My original TiVo installation was for a digital cable set-top box. Because the box lacked a serial input port for changing channels, I had to use the infrared blaster (a three-sided cord with two infrared output lights that pretends to be a remote control). This worked without a hitch.
When I switched to DirecTV, the installation included a Philips DSX5353 receiver. That box also has no serial input port, so I hooked up the IR blaster. Unfortunately, the satellite box was terrible at receiving the signal -- at least 20 percent of the time the channel wouldn't change even though TiVo thought it did, causing it to record the wrong programs or dead air. None of the tips from TiVo's Web site made it better -- I moved the cords around, built an "IR hood" out of cardboard to shield the signal, and tried all of the channel-changing speeds.
Because some of the least-expensive DirecTV receivers include a serial port, I asked the company to swap receivers. In keeping with its spotless record of atrocious customer service, they wouldn't consider it.
Finally, I broke down and decided to buy two new DirecTV receivers that had serial input ports and cords that connected them to the TiVo.
After doing some research, I found that several cheap receivers include serial ports for controlling the box. The port's usually called a "low-speed data port" and requires a $6.99 "home control cable" from the TiVo store.
The RCA DRD 435 is an inexpensive receiver that has a low-speed data port, as I verified from this product shot. Prices vary wildly on the Internet, but I found it selling new for $31.99 from SpectraVox.Com, with discounts for ordering two.
The receivers and cords arrived quickly and were installed in less than two hours. To hook one up:
DirecTV's customer service rep tried to tell me that I was committing to another year of my existing TotalChoice subscription by activating the card.
When I said this was unreasonable because I bought and installed my own receiver, the rep surrendered quickly and said the requirement would be waived.
The new channel changer zooms. The RCA DRD 435 also has a feature I didn't have before: on-screen caller ID.
Though $50 isn't a bad price for reliable TiVo service after a year of needless suffering, the moral of this story is to never add cable or satellite service unless they give you a box with a low-speed data port.
I didn't know there was a necessity for such a thing..I have a nice page with info on DirecTV and its features..Check it out: www.satellitesweeper.com
This is very helpful. About 9 months ago I had the dilemma of Tivo with a unreliable IR interface to a Direct TV receiver. We ended up going with Direct TV DVR for one tv set. I like Tivo better. This will allow us to install Tivo on the other set. Seems odd Tivo doesn't have a link to this.
I had a similar problem a few years ago between DirecTV and TiVo. I bought the RCA 435 receiver for the serial port, and while it works great, I have an even worse problem: This receiver loses its programming every few hours to every few days. I bought a replacement and had the same problem. I contacted DirecTV and they said it was a known problem on this older box: Its memory overflows causing a crash that can only be fixed by pulling the plug for a few seconds. They said that there was no fix for it.
So if anyone knows of another receiver with a low-speed port, please let me know! (I have a 13 year old Sony SAT-B2 receiver for my older TiVo, so that model won't work for me as the remote can't control 2 units of the same brand/model as far as I know).

The DirectTV model D10 (DirectTV gave it to me f/free when my original box died, so you know it's cheap) also has the serial port.
