Comcast was on Rovi's guide data at some point, but switched to Gracenote, likely because of the constant law suits from Tivo.
Yeah, after all those years TiVo spared Comcast from its lawsuit binge on everyone else regarding the "Time Warp" patents. Comcast's lame attempt to integrate TiVo--or at least the TiVo UI--was sure insincere, and TiVo finally came to realize that when Comcast just up and ended the attempt. So, TiVo found some OTHER patents with with which to sue Comcast.
Meanwhile, DirecTV had it iron clad agreement from TiVo NOT to sue DTV for infringement of ANY of TiVo's patents in exchange for DTV developing the THR-22. I'm sorry, but I was not on TiVo's side on its decision to sue everybody (including all the DVR makers) but Comcast and DTV, entities who had agreed to work with them--just as Tom Rogers had
PUBLICALLY promised any company that would "take our call. But if they don't, we intend to sue" said then CEO Tom Rogers. So, I could not help but LAUGH as, while in a Quarterly Conference Call, DirecTV CEo Mike White just put down the forthcoming new DirecTiVo THR-22 compared this his coming Genie, along with other put-downs of the THR-22, and there was nothing TiVo could do about such corporate bad mouthing of a product that was supposed to be THE DVR for TiVo loving DTV subscribers. What a LETDOWN the THR-22 was and is, and even compared to the troublesome DTV Genie which was a reaction to Dish's superior Hopper product.
TiVo would have been better served to SUE DirecTV as they did almost everyone else--and better off suing Comcast at that time, as well. The Irony. TiVo was taken for a ride by Comcast and DirecTV--and TiVo did not get
nearly the huge payoff and never ending stream of income it was expecting from Echostar (Dish) it thought it would get with a "gun to the head" judgement TiVo was expecting, rather than forced to settle for a desperate cash infusion just to survive the moment to press on with the other lawsuits against all others after a brilliant move by Echostars law firm that ended up with the Appllet Court admonishing the Marshall, Texas trail judge and essentially ordering a whole NEW trial of TiVo vs. Echostar (a similar outcome in Echostar's favor in the (TVGuide) Gemstar vs. Echostar lawsuit) with both TiVo and Gemstar taking what was offered by Echostar, which was NOT much, but Gemstar, like TiVo later, had so many others they were suing for the same infringement, Gemstar took the quick cash, but had to agree grant Echostar Lifetime rights to all Gemstar patents and moved on, and yes, TiVo also granted Echostar lifetime rights to all TiVo patents in exchange for the chump change, and that was far from the original plan and point of suing Echostar.
Sadly, this abondoning the requirement of a new trial and accepting the terms of Echostar's settlement displayed the path for TiVo's ultimate decline. Now, they were never gonna get the revenue stream from MVPD's and DVR makers paying never ending royalties to TiVo for use of its patents, nor would they get mountains of money in judgements for all the years all these MVPD's and DVR makers had been--supposedly--using TiVo patents. It really was the beginning of the end for TiVo, for all they could hope for were measly settlements to just barely get by.
Although I am told the THR-22 is based on Series 4, the experience looked and felt like Series 3, which at the time of THR-22 often delayed launch, Series 3 UI was truly dated by then compared with the true Series 4 UI at time, and add to that the the THR-22 had virtually NONE of the retail TiVo features like recordings transfers, etc.
