Macrovision on Freeview ABC1?

I'm using an old Philips DTX6371 OnDigital box to receive Freeview. I
recently recorded a couple of shows on ABC1 and the recordings turned out
unwatchable, with no picture about half the time and a picture switching
between colour and black and white the rest of the time. It looked exactly
like the effect I've seen on recordings of Macrovision protected video
tapes.

Is ABC1 broadcasting with Macrovision or something similar?

Which shows were these?

Cannot be Macrovision as OnDigital (and Sky Digiboxes) STBs were
licensed for "limited PPV" macrovision use only (that is they paid Macrovision
Inc. on a "per use" basis for films/events). I doubt if Freeview STBs even
include it now!

Early versions of the Thomson DTI1000 had it turned on for the VCR port,
until a later OTA upgrade. You couldn't record at all. (These versions
had no UHF modulator, either.)

The explanation was that the chipset came with Macrovision built-in, and
enabled by default, so maybe it's more common than you think. It's
possible something in the abc1 stream triggered it - maybe a PPV flag,
if there is such a thing.

Ok - had not realised that this had happened. It is still correct that any
broadcaster deliberately using Macrovision without a licence would get sued
by Macrovision Inc.!
