 From what I can gather off the Internet, closed captions are supported 
by ivtv and the PVR-150/250/350/500 series of cards. The ivtv source I 
have (0.7.0) has an experimental "test" directory with several programs 
called vbi, vbi-detect, vbi-passthrough, etc. Here's what I get when I 
run them:

[EMAIL PROTECTED] test]# ./vbi
00001000, 2304
(and then it just hangs here)

[EMAIL PROTECTED] test]# ./vbi-detect

That looks promising because it's detecting some sort of closed 
captioning. I have no idea what this output means, though. As for 
vbi-passthrough, it just asks for the incoming vbi and outgoing vbi. I 
don't know what the purpose of that is.

Using bttv, I need 4 PCI slots to record 2 channels at the same time (2 
bttv receivers and 2 audio devices)... cutting this down to 1 slot with 
a PVR-500 would be ENORMOUSLY helpful to me, but I need solid closed 
captioning support first. Any help you can provide is greatly, hugely 
appreciated.
