Hi, <br> After spent one week to upgrade linux version and download/compile MythTv, finally I got it running. <br> The problem now is that it can find the channels during the setup, but when I select live tv in Mythfrontend, it shows a black screen with channel/program information at the bottom, I can change channels but all of them are black screens.
<br> I am able to view "live" Tvs via VLC program. And even in Mythtv-setup it scans and found the channels.<br> I looked at mythbackend log, seems problems reported by "ChannelBase" module which have something to do with the tuner, seems in "live" TV, the tunner can't be controlled so the singals can't be
<br>streamed.<br> Does mythbackend calls some "external" (shell command) program to control the tuner??<br><br> I'm running the Mythtv on Fedora FC8 and the mythtv is the newest version I can get this year(2008).
<br><br> Thans a lot<br><br> Ray<br><br>Following is the log info, I'm using tuner 1 for local broadcasting with an anntena.<br><br><br>[mythtv@localhost share]$ mythbackend<br>2008-01-12 23:06:12.604 Using runtime prefix = /usr
