Question 3:
When starting your computer the error message "No suitable DirectX Provider - Overlay chan-
nel disabled." appears.
Answer 3:
This error message appears when your graphic card's installed drivers do not conform to
DirectX. In this case, you should purchase and install the current driver for your graphics card.
If this does not work, try installing the newest version of DirectX. Afterwards, you shouldn't
have any problem running the software. More information on this problem can be found under
Point 5 of this FAQ.
If you keep getting this error message, ask your graphics card manufacturer if your graphics
card's drivers support DirectX 5.0 or higher and the Video Overlay function.
Question 4:
Why do I need a DirectX graphics card driver with Video Overlay support?
Answer 4:
As with all the current TV cards with Brooktree 848 or 878 chips, the TV data provided through
/Radio+ is integrated through the PCI bus into the graphics card memory without
going through the CPU. This integration is called Video Overlay. Without this function the CPU
would be responsible for writing all the data into the graphics card memory. This would make
simultaneously watching television and working in other applications impossible, as the sys-
tem would be completely overwhelmed. Because Video Overlay works directly with the graph-
ics card, it is necessary to have a DirectX graphics card driver to integrate the television data.
For this reason, a DirectX graphics card driver with Video Overlay support is necessary for the
smooth operation of TV cards.
