Anarchic Harmonics
recorded on long play
these are/were blank tapes with stuff recorded off the telly
Then it's odd that there's Macrovision on em.. If there was Macrovision on the original stream (I know Sky Movies uses it) then you wouldn't have been able to tape at all in the first place so it's odd if the tapes themselves or the recorder out on the Macrovision later..
Still, if you keep getting the message you'll need a stabalizer.
