[mythtv-users] MythTV and TV

Sun Jan 29 01:44:26 UTC 2006

I've been using MythTV successfully for about a year...

But now I want to watch TV.

My setup is as follows:

tooth - FC2 mythtv backend, mysql server, file server, and also houses 
the WinTV card.

hermes - KnoppMyth box.  Mounts files via NFS

I got everything set up, as per the docs.  I can click on WatchTV on 
hermes, and I get a mostly green window with a bar of black and color 
fuzz at the top.  This is the typical thing you see if the TV card is 
not set to the correct frequency/channel/standard.

After a while, the backend says: Couldn't read data from the capture 
card in 15 seconds. Stopping.

That wouldn't be so bad, except that a few seconds later it segfaults 
(log attached at bottom of this message.)

I am in the US, I have everything set to NTSC and so on.

I tested the card in another box, and xawtv can pull in channels just fine.

The really bad thing is that

I've googled about and it seems that the solution is to manually enter 
the frequency tables into mySQL... Before I go that route, I figured I'd 
ask for advice.

Any suggestions?

I have a pcHDTV coming next week, but I'd really like to have this 
figured out by then...
