There is only one "EPG" (now*) broadcast for digital terrestrial TV UK (aka Freeview).
* There used to be others but the business model/funding for these was time-limited.
My guess is that the EPG carousel cycle has changed (simultaneously with the EPG shuffle/new channels starting), and future events/other mux channels are being refreshed less frequently.
Why this causes the Humax SD PVRs to "forget" programmes that it was displaying just a few seconds ago, I have no idea,
