It wouldn't work. Your PVR see's an aerial as a signal so it can change channels etc. when it needs to record a certain channel.

If your PVR even accepts anything via SCART in then it would see it as a video signal, like if you were playing back a camcorder or a VHS, so while it may be able to record that picture it would not be able to change channel so you would have to manually change channel for everything you wanted to record.

Worth a go anyways.
