Hi Barry,

Thanks for your answer.

My native language is german, but I live in France since a long time.

So if I understand you well, regarding live tv should be possible even if 
there is a problem with mythfilldatabase ?

In this case I will first try to get live tv working, and than recording.

http://www.epgdata.com/ is commercial and this should not be necessary. I also 
have a dreambox and it works without any commercial service. (I want to 
replace the dreambox by mythtv because the box is buggy).

I tried a channel scan with a free grabber for Europe, but the result is the 
same: the scan works, I get a liste of hundreds of channels, but I cannot 
regard any.

I do not really understand if a grabber is necessary to watch tv. The french 
mythtv site recommands to choose no grabber in setup.

My channel list is at  

When I choose "watch tv", nothing happens. When I try to record tv, I see the 
channel list, but impossible to watch or record any.

I rebegan mythtv-setup step for step, I cannot see what is wrong.

I shall review the documentation, but perhaps you have an idea about the 
mistake ?
