I'm not associated with PlanesTV, but I'm a regular (and happy!) customer + subscriber with them.
Quite frankly, I'd have been surprised if it were done already. One should not underestimate the work that goes into the editing of video footage -- I know first-hand and I'm nowhere near their level, never mind the extra amount of work they have with incorporating in-cockpit camera footage etc. Leuchars was quite late in the season, I imagine quite a few other DVDs from earlier on are not ready yet, so I think until you see the likes of earlier airshows popping up...
To put this into perspective, there is a company in Belgium that had to produce 1 airshow DVD of a show the weekend after Leuchars and no one received that one either yet, and that's just one report! The company that does the Dutch airshow also takes more than 2 months I believe and I'm not sure if the Kecskemet DVD is already done. Each of those only have to do one airshow, so you can imagine if you have to do multiple. Add to this that in order for them to have the good relationships with teams that get them interviews and exclusive in-cockpit footage which we, paying customers, all like so much to be part of the report, they probably also have to do some return-"favours" to operators with promo-films etc., all of which takes valuable time. Speaking for myself, when I ordered 2 of their DVDs, I already counted on a wait of 3 months.
I realize, may not be the answer you were hoping for though.
