Zap2it Labs is about to shut off the free TV guide listing service used by MythTV, GP-PVR, Media Portal, and other free PVR software applications. As we've been reporting, two separate groups are stepping up to continue offering TV listings.

But neither Schedules Direct nor CT TV will be giving the data away for free. That's because unlike Zap2it, (which is a subsidiary of Tribune Media Services), both groups have to pay to license the data.

Schedules Direct announced earlier this month that their program guide information would be available at a price of $15 for 3 months. As more customers sign up, they're hoping to bring the cost down to $20 per year. This week, CT TV announced that it would charge either $3.50 per month or $30 per year (which comes to $2.50 a month).

Considering CTpvr has long been an also-ran in the world of software-based PVRs, CT TV could become a real money maker for the company. That's assuming free PVR users are willing to pay for TV listings at all and don't just find a way to improve applications that scrape the same data off of online TV guide pages for free.
