No I don't think that is the cause, but worth a try...

The next step for you is to download and install GraphStudio from here, and then follow the instructions bellow:

1. Run GraphStudio as Administrator.

2. Click on the "graph" menu, then click "insert filter" (1st item).

3. In the top left box of the popup window select "WDM streaming TV tuner devices".

4. In the box beside it select "all filters".

5. Take a screenshot ([alt] + [print screen], then paste into Paint, Photoshop or similar and save as an image file).

6. Double click each entry in the list to add each filter to the graph.

7. Repeat options 3, 4, 5 and 6 for the following categories:

"WDM streaming TV audio devices"

"WDM streaming crossbar devices"

"WDM streaming capture devices"

8. Once you have completed step 7, close the popup window.

9. Click on the "graph" menu, then click "make graph screenshot". Paste into Paint/whatever as above... to get a screenshot.

Please post the 5 screenshots here.

If you don't understand the instructions then just ask and I'll try and explain in more detail...
