[mythtv-users] Timeout Scanning 0 -- no signal

Sat Feb 2 17:43:55 UTC 2008

Miroslav,

I had this very same problem with an ATI HDTV Wonder card. The fix for 
me was to download and install the proper firmware for the card. I would 
have figured that such firmware would have been included with the 
distro! Anyway. I'm not sure where to get the firmware package for your 
HD card, that you will have to find on your own. I found mine listed on 
the Mythtv wiki for another card that uses the same firmware as my ATI 
HD TV Wonder card. So keep this in mind!

Good Luck and hope this helps!
