unfortunately I'm not able to run in best way GSspot however Ithink the problem is about the codec this is the message that GSspot give me
Warning: DirectShow crashed while GSpot was attempting to obtain information about a codec.
This is usually due to damaged, misconfigured, conflicting, or poorly written codec drivers. It is possible, perhaps even likely, that other media players will crash when they attempt to play this file as well, as most of them will also use DirectShow. GSpot was able to intercept the crash, and has attempted to identify the codec or filter involved; uninstalling or reinstalling this codec or filter may solve the problem.
The codec was tentatively identified as:
Unknown video codec #8
How can I fix the problem?
