Question 3:
When starting your computer the error message "No suitable DirectX Provider - Overlay
channel 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 TerraTValue 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 system would be completely overwhelmed. Because Video
Overlay works directly with the graphics 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.
