Suffolk Trading Standards began investigating after receiving a report of fake cult and classic DVDs being sold online.
Test purchases were carried out and the discs analysed, which confirmed them to be counterfeit.
Titles examined included Wonder Woman 1984, Shazam, X Men Apocalypse and TV programmes The Strange World of Gurney Slade and Dial 999.
More than 40,000 copied DVDs were seized from his home in October 2021 along with computers, disc burners, a colour photocopier with print outs of DVD box paper insert sleeves, and address label stickers.
Analysis of the seized computers found Williams had sold fake DVDs when attending film and TV fairs, mainly in London, making up to £1,500 per fair, and that he had a wide network of customers in the UK and abroad.
Williams pleaded guilty to one offence under the Copyright, Designs and Patents Act 1998 and one under the Trademark Act 1994.
Graham Crisp, Head of Suffolk Trading Standards, said the original complainant, a UK company called Network Distributing Ltd of London, would purchase copyright licencing rights and restore and remaster the content of classic TV and films for DVD.
However, the company ceased trading in June last year with the loss of nearly 30 jobs.
