When I worked in the VOD industry we never almost never did a precheck of the files. The content provider (Lionsgate in this case) would upload the files that would then get ingested by the CMS system for normalization and transcoding. The most check the distributor did was add metadata marks for ad breaks and random checks for transcode quality.

I set up custom ingest workflows many cable companies around the world and they all worked the same. You just had to trust that the providers sent you good copies and get them to fix their shit if it was wrong. Most of the time it was bad metadata (episode description, ect).
