The AVerMedia M733A PCI Analog driver allows Windows to recognize this internal analog TV tuner/capture card and communicate with its hardware. Installing a compatible driver helps supported viewing or capture software access the card’s analog video and audio functions.

Key Features

• Hardware recognition: Identifies the AVerMedia M733A PCI Analog card so Windows can configure it correctly in Device Manager.
• Analog signal access: Enables compatible applications to use the card’s supported analog inputs for viewing or recording.
• Application communication: Provides the connection between the AverMedia hardware and software designed to work with its capture capabilities.
• Device configuration: Makes driver-supported settings available to Windows and compatible utilities. Available controls depend on the driver version and application.

How to Install

1. Check your Windows version and architecture. Before downloading, confirm whether you use Windows 11, 10, 8, or 7 and whether your system is 32-bit or 64-bit. This is legacy PCI hardware, so verify that the specific driver package explicitly supports your operating system; compatibility should not be assumed across all four versions.

1. Confirm the card is detected. Open Device Manager and look for the AVerMedia M733A PCI Analog or an unidentified multimedia device. If its identity is unclear, check the hardware IDs under Properties > Details and compare them with the driver package information.

1. Download and extract the matching package. Save the driver locally, then extract it if it is compressed. Read any included installation notes before proceeding.

1. Install the driver. Run the supplied installer with administrator permissions. If no installer is provided, right-click the device in Device Manager, choose Update driver, select Browse my computer for drivers, and point Windows to the extracted folder. Do not force an incompatible driver or bypass driver-signature protections.

1. Restart and test the card. Reboot if prompted, then check Device Manager for warnings. Open compatible tuner or capture software and select the card as the input device. The driver alone may not include a viewing application, and reception requires a suitable analog signal source.

Common Issues and Fixes

• Install fails or rolls back: The M733A is a legacy PCI analog tuner/capture card. Run the AVerMedia setup as administrator and in compatibility mode for the Windows version the package supports. If Windows blocks an unsigned driver, use a signed package or a supported OS/VM.
• Device not detected: Power off, reseat the PCI card, try another PCI slot, and check Device Manager for an unknown multimedia device. Install motherboard chipset drivers and confirm the card appears before running the driver setup.
• Version conflicts: Uninstall old AVerMedia TV/capture software and drivers through Device Manager, including driver removal, then reboot and install only the matching M733A package. Avoid mixing newer AVerMedia drivers with this legacy analog card.
