I am presuming that you have veoh player installed on your mac and this is what it says:
The Veoh delivery service (veohd only on OSX) This is a service (or daemon) component that runs in the background and is responsible for downloading and uploading content. It periodically contacts Veoh servers to keep up to date. This component communicates only to the Veoh servers and sends only that information required to upload and download user requested content. This service is required for Veoh to operate.
