"TV Guide On Screen, Guide Plus, Gemstar supprt works"4.0 starson by Specifics
Pros: Once enabled, TV Guide devices update their clocks and guide data
Cons: Difficult to configure
Summary: This DTV converter works as advertised, provided you configure it correctly as the manual is not completely clear. The VBI data for TV Guide is well defined on video lines 13, 14, 15, 16 of field 1 and 13, 14, 15 of field 2. Once set for TV Guide data, you cannot change channels or turn the unit off. This insures you TV Guide device once turned off, can recieve one of the four data downloads daily. Data Downloads consist of todays, tomorrow, and a week from today, so it will take at least 6 days to receive the complete data. Set it to download every other day, (a manual operation), and you will not be disappointed by the TV Guide service. Or just leave this DTV receiver always connected to the antenna input and left configured for the TV Guide (Host Channel PBS HD or CBS HD) service, and use a different type of DTV converter to view channels via the Video/Audio input of your device. Note: most TV Guide on screen devices do not decode the HDTV signal and this setup is required.
