The football league games are filmed in standard definition. There's 30 odd games every weekend so freelance cameramen across the country record the games and drop the tapes at the local BBC office or other designated feed points (bt tower or IMG) The highlights are then clipped up and sent down the line in time for the football league show.
The club do not have easy access to the tapes or the highlights files without having to pay a source fee. So, Oldham have gone to a lot of trouble to repurpose these games to make a DVD for Christmas. The production costs of editing, sleeve design, printing, discs, cases and duplication often prevent clubs from bothering with season review DVDs. Production companies demand club shops buy a certain number of units (eg 500) to make any kind of reasonable profit. Even certain Prem clubs like Wigan struggle to sell that amount. The option to make it inhouse is not always viable due to the reasons mentioned earlier.
Oldham haven't had a DVD out for a while so hopefully this'll make a good stocking filler for Christmas and make a few quid for the club.
P.s very few clubs if any release season reviews on bluray. I imagine it might start happening soon but only the top prem clubs.
