I'm seeing discrepancies between TiVo's guide data and that of Zap2It TV for a number of channels as of October 1. Channels I've noticed with screwy data are:
There might be others, but that's ones I've noticed. Problems I've seen are:
1. Guide data simply being wrong, where the wrong show is shown airing at the wrong time.
2. Guide data shows the correct show at the correct time, but there is no detailed program description so it just shows generic data.
As such shows are getting scheduled at the wrong times in addition all airings of a show being aired.
For example, I have a season pass for Robot Chicken on Cartoon Network. Compare TiVo's listings
to Zap2It's listings
Basically it looks like TiVo's guide data is wrong or not updating for some cable channels.
