AVSourceFilter.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AVSourceFilter.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like BsSndRpt.exe - to follow. These files were created so that multiple programs (eg. DVD Slideshow Builder Deluxe) could share the same AVSourceFilter.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when AVSourceFilter.dll is attempted to be loaded either when DVD Slideshow Builder Deluxe is starting up, or in some cases already running. Some of the most common AVSourceFilter.dll errors include:
- Access Violation at address - AVSourceFilter.dll.
- AVSourceFilter.dll could not be found.
- Cannot find C:\Program Files (x86)\Wondershare\dsb_deluxe-cnet\AVSourceFilter.dll.
- Cannot register AVSourceFilter.dll.
- Cannot start DVD Slideshow Builder Deluxe. A required component is missing: AVSourceFilter.dll. Please install DVD Slideshow Builder Deluxe again.
- Failed to load AVSourceFilter.dll.
- The application has failed to start because AVSourceFilter.dll was not found.
- The file AVSourceFilter.dll is missing or corrupt.
- This application failed to start because AVSourceFilter.dll was not found. Re-installing the application may fix this problem.
Your AVSourceFilter.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with DVD Slideshow Builder Deluxe), or deleted by a malware infection. Furthermore, AVSourceFilter.dll file corruption could be caused from a power outage when loading DVD Slideshow Builder Deluxe, system crash while loading AVSourceFilter.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
