Sound, but no video

Hello,

I just installed ogle 0.9.1 from source on my Slackware 9.1 / 2.4.20 system. 
  I have an ATI Radeon All-in-Wonder card, and I use the GATOS drivers, and 
I can watch TV using avview (which is part of GATOS from what I understand).

But when I run ogle, it doesn't display any video.  I get just a black (not 
blue) screen.  I do hear the audio, though.  Here's the output I see in the 
terminal window:
