I have a Panasonic E50 DVD recorder which works fine for normal recordings. However, I would like to make copies of a few of my commercial DVD's. Not for commercial gain, just for my own use (honest !) I have a Toshiba 3109 DVD player which has been "chipped", which not only makes it region-free, but it removes Macrovision too. However, when I try to copy a commercial DVD from my Toshiba to the Panasonic, the Panasonic says "Cannot record this disk". If I set the Panasonic to record, then press Play on the Tosh, it stops and displays the same message. This isn't Macrovision, so what is it ? Added later: I think it is Macrovision. It seems that Macrovision has moved on a little since I last came across it. Early Macrovision just put a spoiler pulse in the syncs to confuse VCR's, now apparently there's other things inserted into the syncs, which are recognised by DVD recorders. So it appears that my DVD player isn't putting out the spoiler pulse, but may still be outputting the other stuff.
