Yes, charbuffer with color & positioning info. Out of my head all 
filelayout is defined in frame.h.

Only one program can access the vbi at the same time so that is correct.

I presume you did get teletext with the patched AleVT?
I don't know about this AleVT patch, but you could try to apply the same

the part that is doing the vbi grabbing nitty-gritty).
