Hi-

I am using MythTV 0.18 on Debian Etch w/ FusionHDTV5 Lite card. I can use 
mythtv-setup to detect the OTA channels, but when I use mythfilldatabase 
(w/o any parameters), some wget related stuff fly by, but in the end, it 
complained that mythbackend is not running. When I ignore the error and 
start mythbackend, it first complained that :

2005-12-29 16:02:48.184 DVB#0 ERROR - Unable to find channel in database.
2005-12-29 16:02:48.184 DVB#0 ERROR - Failed to get channel options for 
channel 3.

Then I moved on to start mythfrontend and "Watch TV", I got only blank 
screens and frontend console said:

I noticed that it said no PID set and with the atscscan from dvb-apps, I did 
get some PIDs. But the problem is, the mythtv scan process seemed to be a 
black box, and I had no control over details of it. So my questions are:

1. When running mythfilldatabase, according to the setup guide in 
mythtv.org/doc, it is prior to starting backend, but why did it complain at 
the end? Does that affect filling scanning result into database?

2. Is there a way to manually enter channel informations? Or is there a 
solution to my problem (only using mythtv-setup/mythfilldatabase)?

I googled the problem and saw some one with same experience but there were 
no solutions followed. Thanks in advance.
