You may try downloading and installing the latest available drivers for the device according to the make and model and check if this resolves the
issue. You may refer to the below link for assistance - http://www.avermedia.com/avertv/Support/Download.aspx?Type=Software
If the issue still persists, you may also try installing and using Windows Vista or XP drivers in compatibility mode on Windows 7 and check if you
are able to resolve the issue -
If a program written for an earlier version of
Windows doesn't run correctly; use the Program Compatibility Wizard to change the
compatibility settings for the program. To change settings for a program manually, use the individual program's Compatibility tab.
